Ooh err missus.
Thanks for all the help, everyone. The bolts further up the handles/arms are definitely M8. But it wouldn't surprise me a bit if the one I want isn't imperial. I will check further.
You may regret not ordering 5/16. Apologies if my previous post came across as pedantic but I was only trying to help.![]()
3/8 is 9.5 mm
5/16 is 7.94
Because of my work I keep most imperial sizes and a few metric sizes in stock. My offer of help is still available.
Whatever it is, this lot will almost certainly have it:

Brilliant shop, just down the road from here. If by tomorrow you haven't been able to id it definitely, post it to me and I will take it into the shop for you and get them to match it.
Cheers
Jimmy
