These are stock floats with data plates and are off an early 180. Struts could be cut down to shorter for Stinson or other. There are pump out fittings but I think a couple of the plastic cups need replacing. There are dual water rudders; streamline tie wires on the front and cables on the rear. I forget what the horizontal diagonals are. The front bumpers are off and need replacing.
I think the pictures show most of the blemishes. They were reasonably tight when I last used them about 10 years ago because I left it floating for a week at a time with very little pump out required.
