Bulgarian Mystery

[Herb]

One of the Lugers in my collection has mystified me for many years. It is a Bulgarian 1908 Commercial Model. It does not have the upper lanyard loop or well nor a stock lug. It does have the drill holes for the lower loop but there is no loop there. The grips are of the standard military style and cover the lower lanyard loop holes. The mystery is that there are no proof marks whatsoever on this piece. It has a five digit commercial serial number in the 50,000 range. The number appears in it's entirety on the front of the frame and under the barrel. The last two digits of the serial number appear on almost all of the smaller parts, with the exception of the trigger side plate which has three numbers, only the first of which appear in the full serial number. There are several small (1mm) numbers that appear on several places on the frame and a .8 that is on the lower side of the barrel frame. Most markings that are normal are missing, ie; no date, no manufactures markings, no land markings on the barrel (8.81--8.85). The only possible markings are in the forward frame housing, a 'G' over 351. I visited with Ralph Shattuk about 6 years ago and he agrees that it does appear to be a Bulgarian commercial but he was unable to provide any other info. I have the following references: Jones, Datig, Kenyon, Walter and Costanzo and only Datig comes close but the serial nember range for a Bulgarian commercial is not accurate. The machining of this pistol is immaculate, it is of a high luster as if it had been polished but under a jewlers loop all of the maching marks are there. It has some 'plum' color on the rear of the barrel frame and there is no 'straw' on any of the bright parts. The extractor has the Bulgarian Cryllic markings but the safety well does not although it is milled where it shoud be. All of the internal parts are as new, brightly blued and unused. The main spring is of the new type being coiled rather than leaf. The magazine has a black plastic bottom, a coiled spring and is marked with the Mauser banner on the backstrap and is of a very high polish. This Luger appears to have come off the assembly line yesterday, it is the most beautiful one I have ever seen. I can't sleep trying to guess what this is, It's getting on my nerves, HELP ME, what is this thing??
