These were the only swings in all public parks in the Slide the wooden bar down after the child was seated. The later models were the same except made of metal linked chains to attach to the hooks on the chair and the metal draw-down protector
Roller blackboards and the wheeled ones, our science teacher used to put the kids who didn't behave behind it lol been there a few times myself :) not a very popular teacher i think the whole class would have been behind if he had his way hahaha
later Dad would make them frm the old wooden sewing cotton spools with 4 tiny nails hammered on top. We then used off-cuts of coloured wool and one of Mum's crochet hooks. Lots of fun and we called it "French Knitting".
