Loop Knot Discovered in the Wild

Firstly. Please excuse the lack of apostrophes and commas (some conflict between this platform and my Mac)

Ive posted this up on Chit Chat previously and had a lot of fascinating and very helpful replies, so now I feel confident to post it up here.

I first came across this loop when I was using a sailing-clubs dinghy in Staffordshire England, probably 15 years ago now. Being interested in knots and rigging I found a rather elegant loop tied in one of the halyards. Having not come across it before I spent quite a long time teasing it open until I could copy it accurately using a spare piece of cord (there was not another example on any of the clubs boats).

Its such a beautiful loop that I started using it usually as a semi-permanent loop on standing and running rigging. Ive found it to be a reliable and secure loop. Its exquisitely neat with a perfect lead. Its also very easy to tie and so useful in attaching carabiners and anything with an eye. I simply tie an overhand knot then pass the working end through the eye and complete the loop as shown in the image.

Yet I still havent been able to find a documented example of this very useful and aesthetically charming loop.

My thoughts to this point have increasingly leant towards the knot being an incorrectly tied or ad hoc loop which just happens to work. For me it works beautifully.

Any help would be greatly appreciated.

Thank you SecretTed. At last, all has been revealed!

It has a sharper-than-possible initial bend in the SPart,
and a 1dia bend of the tail in exiting --something that
firm ropes will not happily do. And do you not find it
tending to jam?
