Ok, a quick horseback guess without being able to look at the gun- and worth every cent you're paying me (nothing)...
Rough guess is about $450- $550, much less if the condition is bad or the numbers don't match. However, you wouldn't likely get much more than about $350 from a shop or collector unless the condition was perfect.
Just my quick guess. Others may have a better opinion.
You know how you can tell I haven't been here in a couple of weeks? There was a post about an antique .32 pistol, with 7.65 Auto right in the title, no less, and I didn't reply...
I loves me some .32s...
