Hi all, I was wondering if anyone has seen a diagram of the 17-pounder gun identifying its various parts? Ideally for the Mk II, but I suppose even the Mk I would be useful. As always I am looking at this through the lens of the Archer; one issue reported was that when the gun was at maximum elevation the recuperator was very exposed. This was supposedly corrected. I've noticed a small part added in a number of photos of Archers and I'm wondering if that was the fix, but without knowing where the recuperator was and how it would be positioned when the gun was elevated, I don't think I can really figure this out for sure.
