This would be items like aluminum angle for stiffeners, chines, the rounded extruded angle for the Gunwalls, Keel stock, etc.
The generic angle can be obtained from Wicks or Aircraft Spruce, but the other extrusions are not as easy to find.
Also, if anyone has any parts (bulkheads, hatch frames, etc.) available from this type of float, I may be interested.
Any help would be appreciated.
