Hi there,
Your photo looks a bit, I emphasise 'a bit', like a Ross-Courtney termination.
I use them in the terminal chamber of the motor on my ML7. They have the advantage of not having a tail like the modern crimps but they also have the disadvantage of being, apparently, extinct!!!!
If you locate a source, fill your own requirements before blowing the gaff!!!!!!!!
Best regards,
Swarf, Mostly!
