If someone has the figures for the 260 and the 300 circa 1972, I'd
appreciate seeing the data posted here for the gross weight and typical
useful loads.

The 1972 PA32-300 that I flew had the following numbers:
Empty weight: 1810.0 lbs
Basic weight: 1926.4 lbs
Gross weight: 3400.0 lbs
Useful load: 1473.6 lbs
