Made in 1920.
It was produced in 1974.
That is not the serial number. You are looking inside the crane, but the serial number is on the butt.
Around 1950.
You must provide the serial number.
The best that I can say is that the Lefever Nitro special was made from 1921-1948.I do not know if the serial numbers to year of production is available in the public domain.
If your rifle is a model 1894?then the serial number would place your rifle production date as 1921.
Production date is 1977 for serial numbers: 19201M-59999M. Don't know what the X is.
Glocktalk has a serial number sticky
1877 if it's a Single Action Army. Nothing special about the serial number.
About 1913 for a Colt police positive special with that serial number.
If you would be kind enough to supply the serial number to your rifle,I would be able to supply the year of production.
Your serial number places the year of production as 1978.
