Unfortunately, Llama is closed, and there are no public databases of production dates- even if you have given us a model and serial number. Most were from the 1970s- up to 1984.
Colt
Small, inexpensive 22 LR revolver made in Germany.
No known published data.
What year was my H and R 22. Lr model number 929 serial number AX133803 made
No. The case of a 22 WMR is longer than that of a 22 lr, so the cartridge won't fit in a rifle that is chambered for 22 lr.
It was made in 1935.
Bullet weight is immaterial. If it is chambered for 22 LR, then any 22 LR load is fine.
