OK, here is a guess. Stoger used to import a Luger copy made in East Germany by Erma. I believe .32 acp was one of the calibers offered. Something sticks in my mind about buffalo nickle grips as well, but I am getting old, and my beard is turning gray, so good chance I am wrong. I don't think Stoger is in business any longer, not sure about Erma. Get on one of the sites like Gunbroker and look it up - there is a good chance someone has one for sale.
