Dunstall Wheel Bearings

Anyone out there have a cross reference number for a sealed wheel bearing to use at the local bearing supply house for a Dunstall dual disc set up for my Commando? It is a Hoffman P7496 made in England. Otherwise anyone know where to buy a set of these?

Thanks,

Hoffmann Ball Bearings (R.H.P) The United Kingdom's first ball bearing factory was established at New Street and Rectory Lane in Chelmsford in 1898 by cousins Geoffrey and Charles Barrett and bankrolled by American ball bearing machine manufacturer Ernst Gustav Hoffmann from whom the Company took its name. The Hoffmann Manufacturing Company rapidly expanded and soon achieved worldwide fame for their precision-made bearings boasting an accuracy better than 1/10,000 of an inch (2.5 micrometres) for all their products. Hoffmann bearings were later used in the first transatlantic flights and extensively on machinery during World War I. For many years it was Chelmsford's main employer with more employees than the nearby Marconi Company.

The firm became R.H.P.(Ransome Hoffmann and Pollard) after amalgamation with the Ransome and Pollard bearing manufacturing companies in 1969. The factory that once employed 7500 employees over 50 acres in its heyday was wound down during the 1980s and finally closing for good on December 23, 1989.
