Terminator 2 M1887 shotgun T2

[partsguy17]

I know marushin made a m1887 airsoft shotgun which I believe is discontinued, this looks easy enough to scratch build.. has anyone ever actually built one? are there and measurements? I know theres a ton of reference photos on the interwebs, any input here would greatly help

Thanks!
