Anyway, I have also been collecting for a very long time. When I dig out mechs for games, I keep thinking maybe I should start cataloging them.... so here goes. I selected three painted groups for my first Battletech catalog session.
First is a unit painted in mountain terrain camo, 14 mechs. One failing I have is not putting unit insignia on mechs, something I might change in the future. That means these can be used for any unit I want. Despite having a couple of mechs that seem to be specific to one faction or another, I always like the idea of Comstar acquiring mechs for their own reasons. These could very easily be Comstar mechs fitted out for battling in the mountains of Tukayyid...
Hatchetman, Cataphract, Zeus, Banshee (with the extra PPC), Stalker, Annihilator, Locust, Orion, Javelin, Centurion, Victor, Thug, Battlemaster, Imp. The three in the back are older, paint job is not as good, and each is a little banged up :) The ones in the front are the newest, and are painted a bit better.
The next unit is all white Comstar, 27 mechs. One, the Warhammer, was painted white just to be white many years ago, but he fits in with the Comstar stuff. You might notice that many of these are 2750 mechs, which is how I originally started collecting them.
Finally, a small group of mechs painted in woodland camo, 6 mechs. I did not paint as many of this scheme (at least not yet), but I can always expand on it. This is a fairly light bunch (except for that King Crab!), and again, could easily be used as Comstar, or any other faction, as needed.
Not sure when I will get a chance to catalog some more mech units, but I do have a large number of Liao mechs to post at some point, plus some desert type camo.
Until then, go with pulse lasers over AC2s, and it will probably turn out ok....
