Do the third series Diana 58 “serial numbers” in the tap really make sense

[Garvin]

Judging by the number that have come onto the market and given their likely high survivability/limited production window, I don't find it impossible this is a serial number. I don't know where Larry got the 'thousands made' data. The second series 58 was made for far longer (although guns are very scarce). Remember, these top of the line models were very pricey considering how many cheaper alternatives there were.

Edit: not saying Larry's wrong, only that I haven't seen a figure put on their numbers.
