Sorry H, I'm not set up for pics. They really are great guns.
mooncoon, I hope it is that simple. It looks that way, I was hoping someone could confirm. It's the '73/77 I'm working on but my '67/77 is similar ie two (one big, one small) screws.
gabe, the gun is in great shape but when I fire it the case is hard to remove. Upon closer inspection there were a couple of scratches in the chamber. I couldnt remove the breach block so I got a long wood dowel and a drill and proceeded in honing the breach form the muzzle end. It appears to be succesful but now I would like to remove the block to give it a thorough cleaning.
Thanks all.
