I have a mod 53 s/n 4k490xx w/ the 22 lr cylinder.I have read in other posts that the 22 lr cylinder is serial numbered to the gun.Mine has no number on it anywhere.Does that mean that the gun was not shipped with the extra 22 cylinder from the factory.Have had the gun for twenty something years.Gun shoots fine with both Jet and 22 cylinder.Would get it lettered or include pictures but unable to do at this time.Thanks in advance for any info on this.
