Weird No. 32 scope mount

[Lance]

This girl just popped up for sale with a mismatched rifle. WAY overpriced but does anyone recognize the stamp on the inside of the rear leg?

As mentioned in pm Lance, I have seen it once before, but afraid I've not got a clue to whom the JSA relates. I hope someone else can help......!

I had a mount with those markings come through here last year on a No.32 Mk.3 scope for repair
I'll see if I made any notes or took a picture of it at the time.
Not a common marking for sure.
cheers

Interesting. A good deal of care taken over the finishing. That and the low cap numbers say early production, or a very small run obviously. If the other examples had similar low cap numbers we might be on to something.
