Well thats very kind of Desert Rat to say this, but I have to admit I know very little about holsters , Its not something I collect mainly because we are not allowed to own live fire weapons in England, at least not the kind we would all like to own ie WW2 era. Saying that I took a look at the Holster in question, The workmanship that seems to have been done on this piece, is very good albeit fakes have got better over the years, but I would be inclined to say that there is a chance this could be the real deal seeing the age and where it was kept over a long period of time. I would also say that I think you need other opinions, certainly from people who actually collect, pistols and holsters, sorry I cant be of more help
