hi,
I've bought a couple of years of old DWJ magazines.
In an 1974 issue I found an advertisement of a Smith and Wesson M1917 (originally .455 Webley) real revolver converted to 9 mm Knall gas-alarm gun. With PTB!
In the same advertisement there were a Webley Mark IV-9 mm Knall, which I know DO exists.
The Smith and Wesson was priced very high for 1974 (298-498 DM depending on condition).
My question: this gun really exists? I have never seen one outside that advertisment.
