Didn't gather that you have a pair of the mid's/high's.
Other than serial numbers on the 80FR's another thing is that they both have a Black circle around the "S".
There were two earlier versions of the 80FR with either Black or Red circles/dots (containing the "S").
Aside from measuring them with a multimeter in order to see how closely they are matched (typical 16 ohm versions measure in the 6-8 ohm range - long story as to why they don't measure close to 16 ohms) you should also weigh them as the different versions vary approx. 1.5 pounds from one another and the Red/Black dots are not completely definitive as to which version you have as there was some crossover/mixup per the various examples I've owned/measured/weighed.
Tentative savvy buyers would appreciate this info and it would foreseeably increase there value to such.
Anyway, nice save.
