WWII vintage
Well, a model 39 .22 implies to me that it may be a Cooey or Winchester/Cooey. The only thing is Cooey never put serial numbers on their rifles. Winchester did after they bought Cooey around WW II. So therefore I would say post 1964 for your rifle.
The Cooey 39 is so old it sat behind Jesus in the third grade... They were first made around WWII. Hard to tell age of an individual gun because they do not have serial numbers.
There is no such weapon.
By the serial number on the rifle.
you can find them at gun shows or gun shops used.

Send me your email & I'll send you a scan of the manual.
I don't think there is a set value. It should depend on the condition of the firearm.
