A nearly-new and hardly ever used, Axminster SK114 chuck with a 1 1/4" x 8tpi thread. No jaws included, this is just the bare chuck. Current list price at Axminster is 2p under £200.
£100 plus postage (at cost).
The image is a stock-image, I'll photograph the actual chuck later today.
Only selling because I've just changed my lathe and have gone from an imperial to a metric lathe, so don't really want to use an exert-thread adapter.
