Pratt Burnerd 1210-01305 3 Jaw Self Centring 5" Chuck

Made In England.

Suit Myford / Boxford type lathes.

1 3/8" diameter hole, has a backplate fitted, can't be 100% sure but looks more like a Boxford fitting than a Myford, but you can fit your own one on to suit.

2 3/4" body thickness including backplate, 2 5/16" without.

Used, jaws have the slightest of wobbles, barely noticable and when tightened up all good.

Overall looks to have had minimal use.
