Are his eyes red? It looks like it. If they are I'd say he was an L190 (which I've looked for in vain all year!) Everyone advertizes L191's (the dull-eyed Royals) as L190's. I can't find a gray/black (not green/black) L190 ANYwhere. Grrr!
I would say it could be difficult to say for sure without knowing the original location it came from. If I was to guess I'd say either L-27 or L-190. My thinking could be wrong though. Hopefully someone can correct me if so!
You're SO lucky! Yes, L190 and that picture you posted without the flash looks like he's gray & black striped, too. I swear-for a year I've looked all over MFK, AquaBid and the vendors for an L190 exactly like that. The sellers keep saying they've got one but when they send a picture it's a green & black striped L191. I've got 2 L191's already, I want an L190!
