David,
If I were looking for a nice 1920's in 7,65 mm...I would seriously look at the nice offering for only $ 1250 on the bottom of this FGS web site...scroll down to the bottom.
It's mag does have a small chip...so maybe hunt down an unmarked or "germany" marked magazine for another # 125 or so.
With some extra time, you could easily find a "proper" holster in nice condition for maybe $ 250...
