Here's a few maybe-vintage cranksets that have garnered no local interest.
SR Apex crankarms - no rings - 170mm - 90mm BCD double very slightly Campy-esque, pretty clean, no gouges, etc but lite brush marks $20
Suntour Superbe crankset - 53/42 rings - 170mm - 144mm BCD double a bit more Campy-esque, brush marks on LH arm heavier plus wear groove on inside. slight FD marks on inside RH arm plus marks around spindle hole suggesting forced removal, but puller threads are fine. $30
Shimano Sante' SLP crankarms - no rings - 170mm - 130mm BCD double #FC-5000, very clean shop worn condition, been on bike but hardly ridden $50
Shimano DuraAce pre-SLP cranks - no rings - 170mm - 130mm BCD double #FC-7402, RH arm very clean w/slight scatches, LH arm unused $50
