Help ID DWM

Greetings amigos! I have recently acquired my first Luger and would like to ask your help to ID her. As so far as I can figure out from the Dwight Gruber db (Thanks Dwight!), the s/n 6714 will make her an TE (test eagle) of which I have no idea other than the early process of US army choosing new standard handgun. The trigger plate on 6714 calls my attention because it is diferent from all others I've seen in pics, but I think it is a gunsmith work other than factory customizing. here are pics:




Sorry for the awful grips, I will replace ASAP (here in Mexico it is not easy to supply one self at will).

Saludos, and thanks in advance for your input.
