Thanks Kiwi for the information, I wasn't aware of the English model, that's very interesting.

My extra sight isn't the exact same width as the one fitted, so maybe the original has been replaced for additional height or something.

It is very likely that my stock have the compartment for cleaning supplies as well, but is hidden because of the extension and rubber pad. I'll make sure my gunsmith checks when removing it.

Yours sounds like a very nice rifle as well, it would be great to see pictures of it.

Thanks,
Lars
