I have refurbished/restored about five Ludwig hi hats with the Spur Lok footplate. One has the blue/olive label and is quite the heavyweight. Three are the lighter tripod legs, with flat (not tubular) legs. The last has a Speed King footplate, with flat base - the rubber "feet" are on the bottom of the legs, riveted into place - they're more pads than the 'feet' that fit on the end of th leg.
One has remnants of a silver label near the top of the bottom tube.
Anyone know much about approximate eras for these?
How I ended up with these projects.....
