H&R Defender 38 (& relatives) Research
This spring, I bought an H&R Defender 38 (stamped as such on the right side of the barrel). The details are as follows:
The H&R Defender 38's serial number is 6407. This number is both on the front of the grip frame, and on the side of it, underneath the black plastic grips. The number on the side has the letters M H stamped under it. I have still been unable to remove the cylinder to look under the top strap. The number 16 is stamped in small characters on the left side of the frame, near what I take to be the hammer pivot screw.
The company name and address is stamped on the top of the barrel. The back sight is adjustable for windage, and the front sight, which has a brass bead, is adjustable for elevation.
Thanks again, and let me know if there is anything else I can tell you about this gun. I am glad to see there are people interested in them.
