A few years ago some Senior and Mk.1 pistols were re-chromed and nickel plated, and of course ultimately passed off as original once ownership had been transferred through two or three pairs of hands.
How many have such, thinking one the cream of their collection when in fact it is probably worth less than the standard blued item?

In my opinion the less 'repro' there is of anything the better, as the scope for confusion, disappointment and fraud as the years go by is too large.
Also how much satisfaction is there really in having something you know to be a copy, even if it was cheap?
The whole point of collecting is the pleasure in finding genuine artefacts, to enhance a collection?
I would rather go without, maybe for ever, than have something that was made two weeks ago on a laser printer - ugh!
