Here's a neat little thing I picked up ages ago, I never paid it all that much attention. Hopefully, it would have been something my father may have carried, he was a dispatch rider, 72 Wing RAF.
I was recording some of my stuff, and having a good look at this for the first time realised it's a surprisingly well made thing for it's austere time. Hardly an earth shattering item though
I believe it to be a 37 Pat Officers Map Case?
