Need help on a 1914 purchase

[rlbrutke]

Hello...I am new to this forum and would like to see if anyone out there can provide me with some info and a 1914 DWM Luger that I am thinking about purchasing. Here is the info that was given to me by the gun dealer.

DWM Luger with a date stamped 1914 on the top of the barrel.
4" version with stock lug.
All serial numbers are matching (xx28).
28 is also stamped on the gun many times.
Wooden clip is also stamped xx28.

The thing that bothers me, and what is prompting this post, is that on the underside of the barrel where the serial number xx28 is stamped, there is also another 4 digit number above it stamped into the barrel. It reads 8525 which I am assuming is another serial number. Could this be a reworked barrel that was fit to this gun, then stamped with the new serial number of xx28?

Also, I am confused about the stamps on the right side of the barrel. There appears to be four inspections stamps (all in a row). The third stamp in the sequence is the number 63 that has been stamped over with an eagle. The second appears to also be a 60's number (not sure but looks like 61 or even 6D) then has been stamped over that number with an eagle. (I will try to include a pic). The 1st and 4th stamps I am not sure of.

Any ideas or thoughts would be helpful. I am highly interested in purchasing this pistol, but what I want is a matched number 1914 from WWI, not a WWII rework. I also do not want a double stamped barrel.

Thanks in advance for any help on this!
