Might be an Olhausen, they always had the same shape ID plate on the rail cap. The OP could always shoot an email to Olhausen.com. In the FWIW department, I see why the ID plate came off, it pretty much takes up the whole flat portion of the rail cap, so the small portion of oak that should be protecting the backside of the plate was probably broken off by folks breaking and running cues and fingers over that area, which exposed the edge of the plate. I haven't been around many Olhausens, but the ones I've seen had a solid area for mounting the ID plate, not at all like the one pictured. In my humble opinion even if an Olhausen it's not worth much more than the typical Asian import. It still has the big pockets with messed up mitre angles. It needs new cloth, which is 200 to 250 or so, plus you got to pay to get it moved and setup.
