Guys,

I've had a PPK in my safe for some 20+ years and only recently started researching it. I have enjoyed your forum and have learned the following from you..............
The details are as follows:

Wartime finish
loop on bottom(behind mag well)
very good condition 95% ++, as rated by reputable dealers

left side

waffenfabrik walther, zella-mehlis [thur]
walthers patent cal. 7.65 m/m
Mod PPK
E/C
60 degree safety
Black plastic wrap around grip, no cracks, (screw r to l)

Right side

E/N-ejection port
E/N-frame
s/n 405xxxK located on slide and on frame, forward of grip (Walther Banner on grip)

My question isss..........

Where the trigger guard hinges (is pinned at the frame) behind the trigger, the frame thickness measures .631 inches, considerably thicker than other
other pistols I have seen. Others seem to be machined thinner at this point requiring a shorter hinge pin.
After extensive Data mining, I just haven't been able to find anything addressing this observation. Can you help me?

Thanks in advance,
Mike
