Rework?

I just purchased a rework Luger and the top end is a DWM 1915 but I'm not sure what the frame is and I need some help on this. It has no stock lug the ser.# is 29 and it also has a star with 29 in the center of the star just below the takedown lever.It also has a regiment marking on the front grip strap or G.F.M.G.8. The safety marking of Gesichert is stamped in both positions. Can any one help me out on this one? Thanks Don
