Wouldn't normally post here, but I saw this ad;
https://sfbay.craigslist.org/sby/tls/d/j3-hardinge-collet-set/6690682525.html
for a set of J3 Hardinge collets, at a pretty good price. In fact, I'm tempted to buy them even though I don't have anything to use them in. Seems like one of these J series collets is pretty rare, so if this is the rare one, and you need them, here's your chance.
