Found a cigarbox full of chassis parts, probably the first ones I ever bought. Here are pics of the ones I can't identify. Any help would be appreciated.
1) Two small brass tube and wire chassis which look identical. Wheelbase looks short and around 2-5/16", perhaps for 1/32 scale.
2) Two aluminum frames, plus two smaller unidentified pieces.
3) An aluminum drop arm perhaps, with the four holes.
