The Letter M prefix to your serial number indicate that you have a H&R model 922 4th model which was made from 1949-1952.The letter M was the last letter used,so I would assume 1951-1952.
1951-1952.
Impossible to answer without the serial number.
H&R made utility firearms from @1864-1986; 50-125 USD.
Unfortunately, without the serial number, we can't date your revolver. Without knowing the condition, we cannot estimate the value.
