Have: undated (so 1972 or earlier) 175mm Record Strada crankarms
-or-
1984 175mm Record Strada crankarms

I want to trade either for a set of 1984 (4 in a circle) crankarms in 172.5mm
No rings, chainring bolts, crankbolts, covers or anything else included in this swap.

The pics below are of the pre-73 cranks. You can see they have some pockmarks in the finish. My 84's are in a little better shape, but riders, like these pictured.
Caution: both sets of drive side crankarms have started developing the unfortunate but too usual small crack at the spider of the arm.
I have neither drilled nor filed either arm yet to arrest further development.

US swap preferred to keep shipping down.
