To clean it up and make it into a shooter not a lot of work or money should be needed. If you want to make it factory perfect it will one vast money pit.
I passed on a Remington 32 with two triggers in much nicer shape for just over a grand last year. It was a good value but you can not own all fun guns and still have money to shoot with and a current wife that will be happy to see you go shooting.
The early 32's made over seas were made under the Europa name for Hal Dupont. I shot one for years that was one of the first ones made. I understand the started out using a supply of left over part from Remington and made parts as needed. I later heard that Hal just took a Remington 32 over there had them copy it. Which ever was the case it did later evolve into the Krieghoff 32 and then the K-80. So if you want to make a case it has been in production in one version or another for about 80 years.
