These are in rough shape,I think the Structo can be restored,it still winds up and runs but the Circus truck ehh.The friction motor still works on it but the trailer,the animals are supposed to turn when you push it they do not turn.I was thinking of putting them on the bay question is where to start the bidding....or just keep them????

I would not restore them but I would take apart the trailer and see if I could get the animals working again. Can't be that complicated.

I believe in this case, a restored one (professionally) is worth more then the unrestored model. Check out the old Tonkas for examples.

N.B.: That is the famous "TM" logo of Masudaya - Modern Toys.

I would call it "MT" for obvious reasons but most sources agree on "TM" ...

One cannot restore a lithographed tin finish but a coat of furniture polish can usually spruce it up unless it is too rusted.
