I have several 1" micrometers (well, who doesn't?

) but I prefer the dial verniers...they're easier to use...
If anyone is going to make up a database for these measurements, I'll do a better job with my 5...Serial # link to measurements at least...and measure 5 times & take the average...
Now...Why would anyone grind anything off the chamber hood??? I thought the idea of faking was to *add* characters to the receiver...crossed rifle, skull & bones, any date to a commercial...
What would you grind off??? A year date??? Why???
I don't think whipping out a mic at a gun show and measuring a Luger is a good idea...It's sure to get ugly...and will draw a crowd like blood draws sharks...Even if the guy you're talking to is agreeable, the guy two tables over with a boosted Luger will complain about it...
