I was about to put the cylinders back on my 71 roadster and noticed these screws had been safety wired (see attached). Was this done at the factory? It's not a problem, I'm just curious.

This as it should be. Andover Norton will even sell you a length of lock wire for the purpose! That's terribly uneconomical for the punter, but I applaud their approach towards comprehensiveness.
