Mauser Banner 1906/34 Portugese Army Contract

[barr44]

I would like to get some info on my Portugese contract pistol. The pistol has all matching serial numbers except fo the side plate which is no. 59. The pistol serial number is 2509v. Magazine is wood bottom but no visible serial number, the rear grip strap is smooth, no stock slot. Overall condition is good, bluing is good and straw is good. bore is good and function is good. Wooden grips are good but not marked. There is a mark which looks to be a double crown over a U on the front left side of the receiver and on the left side of the tang of the breech block. The Mauser banner is on the center link of the toggle train. The extractor is marked carregada on the left sideand seguranca is on the rear side below the safety lever.
As always I appreciate any info forthcoming, I would send a couple of photos, but not sure how to accomplish that.
Thanks again, barr44
