Well, the verdict is in. The plane does , indeed, have long range tanks.

It also has fuel guages that are improperly calibrated... either the outer senders are inop or the guages are messed up... whatever, the tanks hold 75 gallons of fuel.

The simple method won out... we offloaded the fuel into cans... 74 gallons worth and then fueled from the truck...75 gallons.

The current owner had asked the guy who sold him the plane (on the pre-buy flight) why they only had 93 gallons (according to the guages). He knew the salesman had filled the tanks just before the flight.

The salesman told him that he had standard range tanks, and that was that.

So he has been flying for two years with an extra 300 lbs of fuel.

Thanks to everyone for all of the advice, from the simple to the complex.

Always an adventure.
