Hi, I found this site trying to find the age of some old guns that I own and searching through the old posts has been a big help, but I haven't found much on these.

The Remington is a Model 12-A pump action 22, serial #444445. Does anyone know by the serial number when it was made or can point me in the right direction?

The Mossberg is a model 151k with no serial #. I saw somewhere that these were made in 1951-52, but then I see Mossberg advertisements on ebay from the late 50's with this model listed so I'm not sure how long they made them. If anyone can help with this one too I'd appreciate it.

The last one is a "Premier Single Shot" that has no other markings on it except for the name. I've read that Montgomery Wards sold guns under this name and I don't expect to find any more information on it, but I'll put it out there just in case someone knows anything about them.

Thanks!
