Well, we know at least one person found one. The problem is, with it being a model that was found in the UK, it was likely manufactured in MUCH smaller quantities than one that would have been available in the good ol' US of A.
I've seen numerous modern ones that are similar in design, but it's always a case of "close, but no cigar". :facepalm
Still, I may have to make do with one of those options, as finding the Real McCoy may not be impossible, but it is at least very highly improbable.
Anyway, back to the one pictured... you mentioned the person that owns it. Why didn't you get more info from them when you got the picture(s)? :confused
