I took delivery of my Bobamaker v3 Helmet Kit yesterday, I will put it next to my ASOK GMH CC and put up some pics in the next couple of days.
I will say one thing - the workmanship on the BM v3 is fantastic, when he says it's trimmed, primered and ready to paint he means it! I won't have to do anything (apart from add physical damage for the ROTJ SE look), he even put a removable visor in it for me. Top work!
