I have a similar machine. According to Lathes.uk, Zyto, Pools and Bonds all offered mills of this general design probably made in the Derby / Sheffield area. Mine is labelled "Nottingham Machine Tool" Company.
Regards capabilities, lack of micrometer dials on the feeds is one handicap, but I've used mine for slitting saws and thin side and face cutters on the 1" arbor. Also fly-cutting the radius of smoke-box saddles for a couple of 5" locos, and using end mills as slab cutters. All in all it just about earns its keep.
