I would suggest finding a good gunsmith and asking for a lesson.
H&R model 949 was produced from 1960 to 1985.
1972.
50-125 or so
50-125
Mid 80s
H&R model 949 was produced from 1960 to 1985. The AJ prefix in the serial number indicates 1972 as the year of manufacture.
It depends on the model. I just sold a HR model 949 for $150.
Between 1960-85
Mid 80s
Best left to a gunsmith.
"W" prefix indicates 1960
I own one and they are worth around a 100 dollars
