Re: Iver Johnson Model 56A Starter Revolver
the original model 56 starter pistols have a solid barrel. not only the cylinder has been replaced but the barrel also has been replaced. most likely from a longer barrel version of the model 55 / 55A.
in 1978 the ATF suggested to H&R to redesign their starter revolvers so that they could not be converted to cartridge firearms. this is the last year iver johnson made revolvers so i am sure it was uuggested to them also.
the internal mechanism of the model 56 / 56A starter revolver is the same as the model 55 / 55A, only the barrel and cylinder are different. it would be an easy conversion. as long as the timming is correct there should be no problems firing any 22 long rifle ammo available today, this serial number was manufactured in late 1960's early 1970's. the model 56A was introduced in 1961.
it might be a good idea not to let the ATF know of this revolver. you might want to consider deleting this post. it is not to my knowledge illegal to convert one this way but rules change.
