Fair point about the etched text, but how is someone going to know at all to look for the etching if it’s at all discreet. It’d need to be very obvious to anyone buying the bike second hand from someone’s who’s stolen it or the police.
Indeed, hence I marked, noted the code, and didn’t register.
So what use is it? The police will search for the number and sod all will come up on their database. Same applies to a second hand buyer, they’ll search for it and nothing will come up.
You may as well just write down the frame number and not bother with the etching.
