I remember a wood and leather burning set that was missing most of the specialty tips but did have a few leathers left. One in particular was circular and featured an American Indian printed in red ink. It was already half-traced with the burning iron. I imagined that some other kid must have gotten tired of burning it.
I also had a painted metal Gas Station/Parking Garage assembled and held together with little twisty metal tabs. It had a car elevator with a string winch that would allow you to bring the car up into the parking area and then send it back down to the first floor via a spiral ramp. It was missing a few pieces but had to be one of my favorite toys, ever. I wanted to go inside, use the pay phone, and smell how it smelled.
If the Consumer Product Safety Commission had existed then, I wonder if exposed heating elements, sharp edges or lead-based metal paint would have mattered.
