I had that happen with a Holland Shotgun once, was on the phone to, as it happens a firearms dealer over here in Aus. Found out in general conversation he collected English guns, we discussed what we had.

his ears pricked up at the mention of a Holland, I said it was No 1 or 2 of a pair, he asked what the serial number was and hey presto, I had the other.

His next words were "and the price just went up $5000" to which I replied, "No, $10,000".

He was a happy chap.
