Went to a auction preview, saw a shotgun action that is a new one on me - no camera of course, but here goes.
Action only - barrels, forend, and all wood missing.
Marked - Stevens
12 ga sxs
Top lever
Two triggers

So far so good, now the ????

Hammer gun, but no separate locks.
Think of a box lock action, a bit narrower than usual, and put hammers on the outside.
Anyone??

Stevens No. 225 ?

Cheers,
Jani

Yup, that's it! Many Thanks!
New one on me.
