I'm thinking he might have used one of the scrubbed FBI versions for the base, and that may account for the missing marks.I don't think I'll be buying one (not that I'd need to ). I don't understand why he chose to obliterate the fine details fom his EE3 such as the company name and model and serial number especially when he hasn't on the snub custom thingy based on the mk 3. I appreciate that the serial numbers will never match but the ROTJ prop clearly shows these markings and seems strange to miss them out and a waste of effort alter the mold to hide them. Also why not just do a straight up ESB instead of the custom thing; I'm sure there is a bigger market. If I were in the market for a resin blaster I'd definitely wait the extra time and save a bit more for the sidewinder kits presently available (or stormrider if he's doing them again). In my opinion those SW kits are he best out there.
I like the revolver. I toyed with buying one of these a while back as it looked like an interesting piece but didn't really have the spare cash. Yours looks in great nick though. I agree about the bayonet as being a bit of a stretch and question the stock/carbine attachment too but it certainly looks good.
