The title made me think it was going to be a site listing the banks that allow masturbation in their vaults.
I'm fairly certain the Thompson they have listed sold from a Police auction out of Salisbury a year or so ago for substantially less money then the $48,500 they have on it. I don't know that without a doubt but it looks a lot like it.
Is this it? Sold in September 2016, auction price $37,850.

Edit-it's different serial number than the Salisbury sale.
