These are 1985ish Camco chain drive drum peddles, never broke, still as solid as new- or close to (I have a pair of DW9000s and a pair of TAMA Iron Cobras and these Camcos are VERY CLOSE to those- I thought I'd see a HUGE difference when I bought my DW's, but they were BARELY better, if at all) $50 each, $100 for both.
