Hey there, everybody! Thanks for all of the responses! It's a conundrum burrito wrapped in a mystery tortilla! I'm thinking that it's probably MaxMini, too. I love kit-bashing. So, I've been through Kromlech, PuppetsWar, Zinge, Victoria, Wargames Exclusive,
GW and ForgeWorld. Keep drawing a blank. So, that kinda sucks.
But on a positive note... TTCombat bought out all of MaxMini's product line. So, we should be seeing those bits pretty soon. Just nothing up on TTCombat's site, yet.
Thanks again for all of the suggestions!
Automatically Appended Next Post: Just an update... I did some more checking and I think y'all are right. It looks like the eye slit on the original Vanguard head was filled in with greenstuff and then, I think, one of these Zinge clear lenses glued over the front:

At least, that's what I'm going to try. I think it'll be pretty close.
Thanks for all the advice!
