I am researching a little known Norton of which a small number were produced expressly to conform to AMA regulations.

This is the 500cc, twin cylinder, rigid-framed, Norton Dominator, several of which were raced in the USA in the early 1950's.(They were based on the production version in the image from the 1952 Norton Models 'Export' Catalogue; which I will post as soon as I work out how...)

A few of the production versions exist & sufficient people have stated that they have seen old track-side photographs of the race version at tracks in the USA; but to date no one has actually produced the goods.

My quest is for any data, information, photographs, etc., relating to this machine. Even if it is only a referral to someone else who may be able to help.

Feel free to circulate my request to anybody you feel may have something to offer to my quest.

Thank you in anticipation.
