D.v.p. East german luger

[skeeter4206]

I recently got a D.V.P. luger with the East German eagle surmounting a crown/U on the left frame and receiver. The barrel appears to have been replaced with the crown over N power proof mark with 653 stamped underneath the crown/N which signifies the rebarreling in June of 1953.

After closer inspection of the luger revealed obvious buffing with some areas removing existing markings. On the right side of the receiver appears to be a de/63 stamp which is still half visible. There is something else stamped on the right side underneath the import stamp that I can quite make out.

I'm curious about the buffing off of the original markings, if this was something that would have been done when the luger was rebuilt. The magazine that came with this luger is the 2/1001 style which is proper for the D.V.P. rebuilt luger. The aluminum base has obvious buffing that removed the original markings and then stamped with the SN on the frame and receiver.

I wouldn't mind some feed back from those that could help out with what I am seeing.
