I think this is a Kwikstage scaffolding tower ? very strong/solid/stable 
Really simple and easy to put up

A complete single tower/bay approx 10ft by 4ft (1.3x 3m)
Included are: 4 x 10ft upright poles ~ 16 bracing lengths ~ 2 metal ledgers ?
It has rust and some of the bolts need freeing off but it all fits together well.. please see photos

Cash on collection preferred please
I may be able to deliver for a small charge

Good luck
