Hello, as the title says, I am looking for photos of the interior of the BESA armed Humber armored car, specifically, the weapons and mounts, I have searched quite a bit, with not much luck. any help would be appreciated.

Have you tried Bovington’s library? I’ve not been through the Humber stuff there but they have boxes of material on other British armoured cars with Illustrated parts lists and various manuals and those generally have very good line drawings of the gun mounts and other internal details. I copied a load of stuff on the Daimler there years ago.

Thanks Robert, I would love to visit someday, I'd spend a whole week there. but it is not in the cards anytime soon. I was hoping that someone would know where there was a walkaround including some interior shots lurking around somewhere that I had not seen.

I wasn’t suggesting that you’d need to go there but that you should contact them. I think they have ‘plan packs’ of various illustrations from the docs they hold and although what you get is a second gen copy of what is in the pack, it should suffice for your purposes. The only issue is that the content of each pack varies according to what material they have and what the person creating it decided to include, so not all are as useful as others.
