1939 Luger

Just picked up an interesting rig. a very nice cdg hardshell, an excellent 122 code mag with an eagle 37 proof on the aluminum base, a 655 proofed type 2, and a 1939 42 code in the mid "q" block. According to Still's data, 42 code production started in the r block. Does anyone else have one in the q block? The gun is all matched but has been refinished at some time which kicks the value to a shooter. Just wanted to know if anyone else has seen one this early.
