No published sn data in the US that I know of.
The value of a German made 22 caliber revolver would actually be dependent upon a number of factors. Some of those factors would include the age and condition of the revolver.
It is a cheap German-made revolver of uncertain quality.
10-40 USD
25-65 US dollars
If the revolver is an RG or Rohm, it is worth about $25-50. These were low cost, low quality firearms, and frequenly had frames made of metals other than steel.
50 USD topscan you tell me anything about the value of the gun at all?
Inexpensive, probably built pre-68
A revolver designed for a revolver cartridge cannot, but some revolvers are designed to fire rimless cartridges. S&W and others made revolvers in .45 ACP, the Ruger Speed Six/Security Six was available in 9mm Parabellum.. they use full or half moon clips to hold the rounds in place and load the cylinder, rather than the traditional method of loading a revolver.
no real value. the Rohn is classified as a 'Saturdaynight' special meaning it is not a quality revolver. depending on condition expect $50 - $75
It might be eaiser to ask who in Beligum didn't make a revolver.
