Ok, so here are the most of the remaining potential errata I have for 'Mechs. It's all pretty much for Jihad-era and earlier availabilities. I've tried to group them based on similar issues.
Comstar/WOB stuff based on
Battle of Tukayyid - Supplemental lists (pp. 12-13)
1. Based on this source, Comstar (and also WoB from Clan Invasion forward?) should have the following 'Mechs available in Late SW (renaissance), Clan Invasion, and likely Civil War and Jihad, too:
PNT-8Z Panther:
http://www.masterunitlist.info/Unit/Details/2424/panther-pnt-8zSHD-2Hb Shadow Hawk:
http://www.masterunitlist.info/Unit/Details/2902/shadow-hawk-shd-2hbWVR-7M Wolverine:
http://www.masterunitlist.info/Unit/Details/3576/wolverine-wvr-7m [Clan Invasion, Civil War, and Jihad only, and WoB already has it available]
CPLT-C1b Catapult:
http://www.masterunitlist.info/Unit/Details/480/catapult-cplt-c1b2. JKR-8T Jackrabbit:
http://www.masterunitlist.info/Unit/Details/1656/jackrabbit-jkr-8tTR3075 fluff suggests Comstar should have it for Late SW (renaissance) and Clan Invasion eras. ["ComStar inherited these when they captured Terra, but they used the Jackrabbit sparingly. The few that were deployed on Tukayyid fared poorly against the Clans,..."]
3. HSR-500-D Hussar:
http://www.masterunitlist.info/Unit/Details/1656/jackrabbit-jkr-8tPretty sure
TR3050U has a typo and it is referring to the 500-D when it says the "600-D" (which doesn't exist) "has only been seen among WoB forces," Comstar should not have access to this variant (previous paragraph notes they use the 200-D and 400-D variants)
The next set of issues all relate to what's in the RAT tables in
Historical: War of 3039 for the Draconis Combine. Not sure if any of this is still correct or was retcon'ed. I always remember the lore to be that Comstar gave Kurita mostly downgraded 'Mechs with a few accidental/overlooked exceptions, but the RATs in that book definitely have more than a few LosTech variants.
4. The following are available to the Draconis Combine in the Clan Invasion and Civil War eras but not the Late SW (renaissance) era (i.e. during the War of 3039). If the first two are correct, then
Hist:Wo3039 suggests they should have them available in the Late SW (renaissance) era, too:
HSR-200-D Hussar:
http://www.masterunitlist.info/Unit/Details/1585/hussar-hsr-200-dCHP-1N Champion:
http://www.masterunitlist.info/Unit/Details/548/champion-chp-1nLNC25-01 Lancelot:
http://www.masterunitlist.info/Unit/Details/1853/lancelot-lnc25-01EXT-4D Exterminator:
http://www.masterunitlist.info/Unit/Details/1004/exterminator-ext-4dGLT-3N Guillotine:
http://www.masterunitlist.info/Unit/Details/1338/guillotine-glt-3nBL-6-KNT Black Knight:
http://www.masterunitlist.info/Unit/Details/358/black-knight-bl-6-kntBLR-2C Battlemaster:
http://www.masterunitlist.info/Unit/Details/290/battlemaster-blr-2c(this one actually comes from the Battlemaster fluff in
RecGuide vol. 3 and in the original
TR3050. Former lists it as Theodore Kurita's Wo3039 'Mech and latter list it as a Comstar logistical screw-up)
5. These two are not available to Kurita at all in the MUL, but based on
Historical: War of 3039, they should have them at least in Late SW (renaissance), and likely in the next couple eras, too.
MCY-98 Mercury:
http://www.masterunitlist.info/Unit/Details/4624/mercury-mcy-98MON-66 Mongoose:
http://www.masterunitlist.info/Unit/Details/2208/mongoose-mon-666. The WVN-5N Wyvern is also available to Kurita based on
Historical: War of 3039, but is not available to them in either the Late SW (renaissance) or Clan Invasion eras. Based on this, it should be. It should probably also be available to Comstar in Early SW, Late SW (LosTech), and Late SW (renaissance) since it's the stock SLDF variant (and they're the ones who gave it to Kurita...)
http://www.masterunitlist.info/Unit/Details/3597/wyvern-wve-5n7. HGN-732 Highlander:
http://www.masterunitlist.info/Unit/Details/1514/highlander-hgn-732This one is available to Kurita in Late SW (renaissance), but not after. I didn't see anything to suggest that Kurita lost all of its Highlanders before the Clan Invasion, so it probably should be available in later eras like the other Comstar-supplied 'Mechs. Multiple sources suggest that the Late SW era availability is correct [
Historical: War of 3039,
TR3050U fluff,
TR3039 fluff for Thug 10E]
8. STK-3K Sentinel:
http://www.masterunitlist.info/Unit/Details/2857/sentinel-stn-3kKurita has this variant available in the MUL from the end of the Star League throughout, but
Historical: War of 3039 and Sentinel 3K fluff in
TR3039 suggest that Kurita received both the -3K and -3M models as a new influx of the variant from Comstar, and only a handful existed in entire IS otherwise (presumably from Steiner production?)
9. I honestly cannot figure out if Kurita should have the CRB-27 Crab variant from 3035 forward (currently only has it from Clan Invasion forward):
http://www.masterunitlist.info/Unit/Details/716/crab-crb-27It is not in the RAT tables in
Historical: War of 3039, but... original
TR3050 Crab fluff suggests the only difference between the SLDF CRB-27 and what was given to Kurita is comms equipment (so identical in game terms), and...
TR3050U Crab fluff suggests that the Kurita variants (along with Clan, Comstar, and WoB) are from the original SLDF production runs. So maybe they should?
The next bunch are to give the St. Ives Compact availability some love. I'm wondering if a lot of these got lost because they only RAT I could find for them is merged into the RAT table for Liao in
FM: Capellan Confederation, and they have no listing of their own in
Combat Ops.
10. Based on the RAT table in
FM: Capellan Confederation, SIC should have the following 'Mechs available in the Clan Invasion and Civil War eras:
CTX-3D Cataphract:
http://www.masterunitlist.info/Unit/Details/469/cataphract-ctf-3dSTR-3C Striker:
http://www.masterunitlist.info/Unit/Details/3094/striker-stc-2c [correctly has it available in Late SW (renaissance)]
STR-3D Striker:
http://www.masterunitlist.info/Unit/Details/3095/striker-stc-2dAS7-S Atlas:
http://www.masterunitlist.info/Unit/Details/148/atlas-as7-sAS7-K Atlas:
http://www.masterunitlist.info/Unit/Details/144/atlas-as7-kDVS-2 Devastator:
http://www.masterunitlist.info/Unit/Details/894/devastator-dvs-2 [might also want to remove availability for Liao in Clan Invasion era. Only DVS-2s they should have are the ones they inherit from SIC after 3063?]
11. CRD-4D Crusader:
http://www.masterunitlist.info/Unit/Details/755/crusader-crd-4d (or CRD-4L)
There isn't a source to justify this one, but the CRD-4D and CRD-4L are identical variants, but use field refit kits, and SIC is bordered by both factions, so it would make sense they'd have one of these available in the Clan Invasion and Civil War eras (most likely the CRD-4D variant given their trade relations with FedCom)
Ok, that's probably enough for now! I have one more (much smaller) batch, but I'll wait to see what you guys say for these before posting those, since they have some gray areas in availability like some of the Mechs above.
