very simular in size and design to the US army "shelter half" tent(AKA pup tent).
i bnought one for £20 ten years ago, again very heavy, worse when wet, really good in wind but spending more than a few hours in one gets boring, because of the thick canvas light will not penetrate so a torch is needed to find stuff in the tent 24 hours a day!
after heavy rain, the canvas will be full of water if you touch the sides the water will drip though, i did a 3 day camp with my wife in one of these we gave up due to damp conditions after 1 1/2 days!
probably no ground sheet, so water can run under and into the tent unlike modern "bath tub" designs, the insect net will stop fliying bugs but not crawling ones such as ants!
all in all nowerdays cheaper lighter ones are far better and easy to get hold of, i would consign these to either scouts, or yourself for kit disipline training or a tent for kids to play in, in the garden.
