Code 42 question.

Hello guys,

I have a 1916 Erfurt Imperial Luger with the last two digits "76" all over except the sear and the side plate. Both sear and side plate or trigger plate as some might call it have a "42". The side plate is imperial marked and has a 42 instead of 76 on it. What I am gettin at is this....could the 42 on side plate and sear have been a WWII mauser replacement as I have heard the "42" is a mauser code. Any thoughts on this or am I dead wrong im my suspisions.

Thanks...Bob
