This is my first post and trying to get acclimated to this site. I recently came across a Model 53 revolver with dual firing pins for rimfire and centerfire. It's been impossible since I obtained the gun to locate .22 Jet ammunition or reload brass. I have also not been able to determine the year the gun was manufactured. Have taken it to a couple gun shops and the best they can tell me is that the gun was made betwen 1961 and 1972. Finally, have not been able to locate a user manual for this gun. Any assistance from this group to locate .22 Jet ammo, user manual or manufacture date would be greatly appreciated. I will likely not fire the gun much but would like to obtain a couple hundred .22 Jet rounds. I have not reloaded ammo but have friends that do. However, have also not been able to locate brass and would also need to purchase dies. Thanks for any help.
