'R' prefix indicates 1955
1955. This question has already been answered once before for this same serial number.
From the serial number. There are various references that list ranges of serial numbers for different years.
What year was the H & R 922 6" revolver, serial number E664 manufactured? Thanks
Blue Book of Gun Values can help with how long the Model was made.
No sn data for that model I can find.
"C" prefix indicates 1942
I am showing that HR made a revolver in models 826,829,832,and 922.If you check your model number again it may be one of these.Please repost your question if that is the case.
