Matching Luger question - Don't Shoot!

[Thor]

Is that a word? Anyway, I had a thought! Seldom occurs, I know! Hello fellows, If a guy find another sideplate that has the matching numbers but came form another Luger and he puts it on the Luger he is trying to get all the parts to match, but the take down lever is very very hard to close. He now takes the gun to gunshow and sells it and the new owner is constantly having to use a screw drive to open the take down to field strip and clean the gun and because the side plate doesnt fit properly, this action mars the finish........ Just a thought! And didn't the fonts change a little over time? (I know that is another thought) Thor
