Is that a whitworth thread?

www.latheparts.co.uk will sort you out with a backplate, then you can fit any 4 jaw. ebay is your friend for the chuck itself.
1 1/2" x 8TPI is a standard BSF thread and will be Whitworth thread form.

Hi,
When you have a backplate that fits the nose, you machine it so that it fits the register at the rear of the chuck, which most chucks will have.
Any 4 jaw chuck should be adaptable to fit, a self centering chuck can be mounted on a backplate with a bit of play so that it can be adjusted to
be close to exactly concentric.
