s&w 9mm magazine question

This magazine was among my father things when he passed away. It had seven or eight 9mm rounds in it. As far as I know he did not own any 9mm's. Anyone know what it fits?

thanks,

Randy

Maybe for a S&W model 39?

thanks greatly, it seems identical to images of the S&W M39 magazine on line.

Are you interested in selling it?

Yep looks just like one of the mags to my S&W 39.
