Dwight,
Outstanding presentation !! <img border="0" alt="[cheers]" title="" src="graemlins/beerchug.gif" /> I too went in the safe to have a closer look at the Simson Blank Chamber P08. My odservations are similar to Herb. Here goes:
The sideplate has E/6 on the exterior, nothing on the interior but the trigger lever has E/6. Locking bolt has E/6 plus last 2 of the SN which are 60. Grip panels have the full SN and E/6 on the inside. Axle pin is unumbered & unproofed. Rear toggle has E/6 on the top and a small & lightly stamped E/6 underneath on the left side. No RW stamp. Breechblock has 60 and a Weimar eagle below on the left plus the E/6 on the right side. Hold Open has 60 and E/6, no outside pin. Sear bar relieved E/6 then 60. Receiver right side has E/6, E/81, E/6 and Weimar eagle. Left side shows pistol's SN 1060. Barrel left has RC Proof and E/6, Weimar eagle on right side. Underside of the barrel shows a 6 on top of 1060 then 8.82. Interesting is the front sight base that shows a small E/6 on it's left side. Frame has E/46 on top of SN. Trigger guard has 2 E/6 a large and a small one. Almost is not all small parts have the E/6 proof.
My observation is that grip panels are thicker than most P08s and have a coarse checkering pattern.
I find those Simsons P08 quite interesting as there are quite some variations & combinations of Proofmarks...Sadly enough, few survived
