At that price I would buy it in a heart beat. New here in the states the chuck alone, no collets, goes for around $1300.00. the smaller collets go for around $50.00+. Ask the seller what model number it is, as the back plates are interchangable within certain size chucks. If it is a D1-3 mount you can get a D1-4 or a D1-6 to replace it. If you can get the chuck cheap enough, the cost of a new back plate is worth the price, plus you can sell the old one.

It looks just like the collet chuck that was ordered as part of the tooling package for one of our Harrison/Colchester Variable speed lathes we have at work. Works well enough, but for the other one we have I'm glad we ordered a Hardinge Soldginge(?) 5C.

I sold a lever operated one with a fuLl set of collets going up to 1 1/2" for £150 about a year ago but this was private and not Ebay.

Keyed chucks aren't worth as much as lever chucks as lever chucks lend themselves more to production, you don't need to stop the machine.

That is a version of the Jacobs spindle nose collet chuck. Jacobs no longer makes these or the collets. PBA has adopted the design to use a steel collet.
I have sold sets of the Jacobs on eBay for around $250.00.
The collets go for around $200.00 each new.
The Jacobs do not have a separate backplate and are harder then the hinges of Hell, so adapting to another spindle nose is out. It is possible that it is a D1-4 if they measured pin centers, not the diameter of the pin circle. See if you can get the dimension of the diameter of the large end of the tapered hole. That should approach 2-1/2" for a D1-4.
You can compare the value of this chuck to a Bison 5C chuck at $250.00 plus backplate plus many collets to cover the sise range, and it is a good value.

Alistair, This link was in a previous post. They carry that line and give all of the particulars, including dimensions and US price. I do not know the conversion factor to the pound but htis should help some more.
