Getting closer to done! Ice was picked up on Galatea (like Smoke), and doesn't much talk about her work prior to that, though she speaks passable German. She's pretty good with myomer, and her Whitworth ("Snowflake") has Vestigial Hands (the 0-point quirk) as a result (so THAT's how the Whitworth was able to pack up its chute!). It also has LRM-5s in place of the LRM-10s, which allows it to carry a third ton of ammo (Smoke, of course). There's a stray half ton we're still hammering out...
As far as Smoke's requested changes (pulling the SRM-4 and ammo for 2 Mediums and a Heat Sink), it looks like Class B refits all the way, so:
Remove Ammo bin in LT: 120 minutes
Install Heat Sink in LT: 90 minutes
Remove SRM-4 in CT: 120 minutes
Install Medium Laser in CT: 120 minutes
Install Medium Laser in CT: 120 minutes
Class B Time Modifier: 3
Total Minutes for Refit: 1,710 (28.5 hours, potentially broken up into a 10.5-hour day, a 12-hour day, and a 6-hour day)
Further good news: Since the unit obtained a Heat Sink and a Medium Laser from Renzi's crew, it only takes one of the unit's own spare Medium Lasers to make work. The only hard spot is finding the time to down the Panther... ;)
