This was the first thing to pop into my head too. It seems to be the go to for Comstar art that is not a post-Tuk build.
On that note, one thing I was never clear on is what kind of salvage did Comstar get out of Tuk?
It's tough to say, honestly. There were no shortage of Clan Mech carcasses laying about, one would think (god, imagine dredging the Prezno river of all those flooded Falcon Guards Mechs from their crossing!), but as we know from sources like the Avatar's writeup in TRO:3058 it was tricky getting Clan gear to run for IS technicians. (Thus that machine's hardwired medium lasers, in case of pod failure).
Now, Comstar had more skilled techs than the Successor States, of course- they were maintaining SLDF-style tech, after all, something that by this point only elite house units were being equipped with. But Clan tech might have still been tricky to deal with- especially since getting intact units was likely rare.
So, by volume? Plenty of salvaged Clan gear. How much of it was useful within the first six months? Not a lot, I'd wager. (Factor in that much of what could be moved by the Word when the schism took place probably was hijacked!). We DO know that enough gear was salvaged to equip the 'Invader Galaxy', though I recall that was mostly IS units re-equipped with Clan equipment (and tactics) rather than using actual Clan Mechs.
I'd bet that by the time the Jihad arrived over Tukkayid, there were STILL plenty of Clan units- maybe even Com Guards- laying abandoned for a decade and a half, simply because there's only so much time in the day and a whole planet to scour to find them.
