Jrhead, thanks for the info!

Peter, I'm actually less concerned with the maker of the magazine than I am with the condition of the current magazine itself as it's kind of hammered. It's the only part on the rifle with any wear. In fact, I'm also looking for a new Faz magazine to replace the serialed (matching) mag on my other No5 because it tends to jam on the last round. All of the rifles in my collection are shooters first.

Cheers,
Chris
