Received this today. This gentleman is trying to discern EXACTLY what this is. I hope we can help him out. I haven't had time to look at the link yet, because I have been working all day (big weekend at our store)! I will take a look right now too.

My name is Mark and i'm from Holland. In the basement of my grandmother I found a bag. A guy told me it was a case to carry a mobile desk with stuff from the Royel Engineers from WW2. Could you help me solve my question for ones and for all? The pictures i could'nt send. Underneeth i put a link to a dutch site of people who tried to help me. Could you please help me?
Thank you verry much.
Mark

Does nobody know what this is?
Greetings from holland.
Can you give us the dimensions of this bag?
To me it looks very narrow, and resembles something like a large map bag. That is just me surmising!
I am still looking around for clues.

That (Map Bag) is what comes to my mind also at first look, but not certain.
Good Luck!
