Hello All,

Is the Simson 16 ga sxs frame a true 16 ga frame ?
Or is the 16 ga built on a 12 ga frame ?
The gun has German proof marks and an 856 date code ( Aug 1956 )
Same dimensions are:
1.09" firing pin centers
2.14" across the side clips (Widest oint on the standing breech)
1.59" across the action at the bolster ( Widest point just below standing breech )
0.89" depth of the action ( Action flat to center of trigger plate

Thanks
