This one. Davis D32 in powerhouse .32 ACP.
I think I gave $50 for it. It actually worked for a while, but broke a long time ago. It won't fire anymore, not sure what's wrong with it.
It sits on a curio shelf as office decor now.
Police auction in the early 1990s. Picked up a half dozen guns for under $200.00. Cheapest was a Gercuda 7 shot .32 S&W revolver for $5.00. Yep, the transfer fee was more than the gun.
