Your serial number indicates that your Ruger Single Six was made in late 1975.
1951 Model 37
Impossible to value with just the serial number.
It could be any where from a single digit to a six figure serial number located on the rifle.
Q Model - 1960; K Model - 1961; The serial number must have a Q or K at the end.
It is a Model 1885. With the serial number, I can provide you with the specific year of manufacture.
about 1905
If your serial number has no single letter prefix to the serial number,then it was made between 1939-1947.Most likely 1940.
There is no way to answer your question, due to lack of information on make and model. Serial numbers are not unique to a single firearm, and several different makes and models may have the same serial number.
I have a J Stevens Springfield Model 15, .22 single shot, and there is no serial number. I bought it a t a gun store, and the dealer marked my receipt to indicate it had no serial number. There is also no indication that a serial number was removed.
No serial number provided.
if a single acton model then about 1893 (I think)
