I don't collect deacts (don't want a gun if it doesn't go bang , or at least pop) but I've been given the impression that all new deacts have a proof-house certificate , although I don't know how much detail goes on it . I suspect plod will get quite excitable if he finds something that does not conform . He will chuck the book at you ... you know , the one he wrote himself .
Peter , is your "facility" at Warminster open to the public , or by invite only ?
