A pleasing find during my recent break was this Lone Star die-cast breakdown truck. I'd estimate it to date from the 1960s and taking that into account it is in pretty good nick. And yes, the gantry still winds up and down!
I'm not sure what scale it is but I intend to use it with 1/32 figures and I think it'll fit in OK. Here it is towing a battered Dinky (1/35-ish) Jeep.
