Greener MK3 12 gauge 2 3/4"

Good morning folks...can't remember if this is 1st post or not. Been lurking in the darkness for a while now.
Played lots on CGN... I found the forum here much friendly. Usually the same guys, same usernames even.
I digress. A Greener mk 3 in 12 gauge followed me home, pretty good shape...came in pieces. Apparently Martini Henry design is too difficult to keep assembled.
Other than a cleanup ( machining marks were bad), it is missing a striker and it's spring that I can tell. Of course the capture screws as well...to be expected I suppose. I'll try to throw a picture or two up in the next bit.
Regards
Bernie
