I pulled out my copy and it seems like a definite original, it's a white label promo with a bunch of label wear, writing on it, etc., that I found in some junk in Chicago. I'm disturbed by no stamp or anything official looking in the deadwax. The deadwax has handwritten U-1390 the ah la la side and U-1391 on the other side. In smaller letters on both sides handwritten is "BRS". There may have been red wax originals since that was a thing with doowop labels. I think you need info from the kreiter guide at this point, do you know someone with a copy or should I ask someone?
