I have a COS SuperTen with oval badge and serial number 0151. From scanning earlier posts, it seems Ploughman has located these to 1973 with numbers ranging from 0150 to 0275. If you don't have 0150, you can't get too much lower than this one.
Accordingly, this drum is in a time period a little beyond that for which I have specific interest. I'm mostly interested in the Dayton speckled era or very early Fullerton drums ('67-68 catalog and a bit beyond in the transition to borderless Holiday Fullerton tags with serial numbers around 10xxx).
Anyway, if someone is onto these SuperTens, PM me and maybe we can work something out. The drum is in very nice shape with the exception of the bottom hoop, from which some of the chrome has delaminated. I have a clearner, but probably later one on right now that will be included. Need $175 plus shipping or let me know of a potentially interesting trade item. It does sound very good too.
Thanks,
