Sauer made three models in 7.65 (.32 ACP) of two distinct types. The first is a single action, striker fired pistol with a large knob on the rear. Most of these in .32 are the "Behorden" (Authority) model. Disassembly of these begins by pushing down on the rear sight, and unscrewing the knob.
The second type is the Model 38H, which is a conventional double action pistol with a cocking/decocking lever. Most have a slide safety that goes down to the fire position, the opposite of the Walthers. The disassembly catch is in the top of the trigger guard.
They run around $350 for the earlier model, $400 for the 38H. A 38H in .380 or in .22 LR will bring $3500-4000, but those are rare, and I have never seen either. Within the limits of its caliber, the 38H is a good defense gun.
If the gun actually was taken from a Japanese soldier, it would probably have been the earlier gun, as Sauer did not make many of the 38H for export.
