thanks guys........fatboy, where are you located?......my father in law is a fitter&turner/bolier maker so I could either take a NOS one and ask hime to ask a fabricator friend or if fatboy is too far away, i could try to cut the good one out and do that and its mirror, assuming there's a difference (the rare spares repro looks to b all of 2 folds). Once we can find a fabricator who can actually do it, i'll ask him to make plenty!
