Sorry about the theft. I missed the difference in slang, as I saw "nicked" and thought paint chip, instead of theft.
I had a Fuji stolen twice. I got it back the first time after seeing the guy riding it on the navy base. I convinced him that I had the receipt with the serial number and he had better give it back. After he did and I put it back in my room, I went and got the base cops and ID'd the guy. He was carrying weed, so he got in even more trouble and ended up getting discharged. The second time was on a different base and it was just gone without a trace. It was in a rack full of bikes, but there must have been something that made mine an easier target. When I got a new bike, I stored it on the ship.
