To my knowledge the most used tent in the AZW was the "bell" tent. This tent, as implied by it's name was round, standing at the single central pole some 2,5m high. Verical side walls were about .6m. This tent slept some 8 - 10 men. Normally white canvas was used.
I wil look for pictures of these tomorrow , which I will send to you, and from them you will be able to gauge more accuratley sizes and proportions.
For larger gathering the marquee tent was used. These had many different sizes.
