Lithgow HT scope rings screw pitch

[Son]

Hi pardon my muddling of the description, but can someone tell me the type of thread used in the rings of the Lithgow HT sniper rifle. They are the last piece of a restoration, and when I know what they are I can make them... and be finished.
Thanks a lot

Since seeing your post I've looked through all my material and cannot come up with an answer. I'm afraid I won't be pulling mine out to measure them, but you could possibly measure your rings and compare with this info...

British Tools & Fasteners - BA Thread Profile

The screws in the scope itself are BA (British Association) thread form. It's likely the screws clamping the rings to the tube are also BA. If you can decide which size, buy a screw and try it gently. They are available- with a bit of searching.
