Tent help

[Smalltownff]

I was given an older "tent" and was wondering if I could get and info on it. It's an all canvas tent. I believe it uses ropes instead of poles. I have not fully opened it yet as I am slightly intimidated by it. Here are a couple of pictures. I know it's not a lot to go on but if you have seen anything like it or have a reference of where I might find some instructions that would be great.

Thanks,
