(it is quite a find...but, I think you'll find that "leather" bar wrap is "faux):
If you examine the wrap closely, you will find a small Hutchinson imprint, at least I did on my Grand Jubile & also on a Grand Touring I used to have. I've heard them referred to as "Pleather" bar wraps & they came in black as well as tan. Always wondered how they were applied as it looks like they were cast in one piece around the bar & brake levers. Both of mine were in remarkably good condition given their age. Don
