Another One

Al,

Curiouser and curiouser.

The Crown-over-N proof (#28 in the markings area of Technical Information, at left), if present, will be found on: the left side of the receiver; under the barrel above the serial number; on the left side of the breechblock (could be very tiny and faint). It makes a difference if the mark on the receiver is upright or "lazy", on its side (see mark #4).

Is the serial number the same on the frame and barrel except for the letter suffix? Or, are your "xxx"s hiding a difference?

It is important to know if the numbers on the trigger plate and locking bolt are on the face or the edge of the part.

When you take your Luger apart you will find, underneath the barrel/receiver, a line called a "witness mark". This is a single mark, stamped with one blow of a chisel-type tool, axially across the juncture of the barrel and receiver. Look very closely at this, preferably under magnification, and see if there is any discontinuity in the mark, anything which looks "funny", which would indicate that it has been rebarrelled.

As always, picures would be helpful.
