Had my FC called in to reprint to take allowance of a new rifle.
Upon return I duly checked the new addition, all OK.
Months later I'm at Manchester airport flying to South Africa with a rifle I've taken before. Customs point out to me that the serial number on my FAC isn't the same as on the rifle !
A single number was out, a 9 instead of a 3. No probs with Customs as they could see it was a likely typo and that I had a ticket to come back. All they would be doing is reporting the export/import of the firearm anyway and would point out the "administrative error" to Lincs Police.
South Africa was a bit more subtle. I stuck with the number on my FAC and just picked up the offending rifle and "read out" the number No problem
Moral of the story is to check everything when your FAC comes back....
PS. On my return to Manchester one of my rifles, yes you guessed the offending serial error, was delayed to the following flight. I went home to Lincoln and the next day Customs phoned, asked for the combination to my case to check it, and then released it to the Airline to courier it to me. One up for combination as opposed to padlocks.
