Once upon a time lenses had fanciful names. Nowadays they've mostly disappeared, just maker's name and specifications.
What about lens numbers? Canon lens numbers might be round the front element, round the base of the lens, or even inside the mount facing the mirror when fitted. I recently bought a new Canon EF 50mm/1.4,and can't find a number anywhere. The lens number is something you usually note to identify it in case it's stolen. Canon even used to register them as insurance.
Have I missed something?

It certainly was a requirement of the old JPI export regulations that all photographic lenses and cameras were to be numbered. Also in the UK it was a requirement by Customs and Excise to have numbered items to be able to trace whether import duties had been paid. I expect that it has lapsed over time, with goods like digital cameras coming from so many sources, making identification by number more difficult. After saying that most stuff has some numeric marking somewhere. Stephen

On my Canon 50mm f/1.8, the serial number is printed in grey on the black plastic inside the mount. It is not all that visible unless you are looking for grey on black.

Thank you for your responses. Like Stephen, I was convinced there would be a number somewhere, hence the query. I just hoped I wouldn't need a screwdriver to find it. Like Peltigera, I'd seen it inside the mount on the 50mm 1.8.
I turned to the fount of all wisdom, eb*y, and among all the 50mm 1.4 for sale, there were some that had actually managed to photograph the serial number inside the lens mount, like the 50mm 1.8.
Back to mine with reading glasses - nothing. With reading glasses and reading magnifier there was an illegible smudge. With a jeweller's loupe it was there, finely engraved on the rear face of the mount and all the same matt black, definitely not the grey on black of the 50mm 1.8.
Anyway, problem solved.
