This early Kodachrome came from the same research as both Mees & Capstaff had mover to set up the new Rochester Research facility after George Eastman bought Wratten & Wainwright, (he had already tried to buy Ilford twice). Other members of the company remained in the UK to found Kodak's Harrow Research facility.
Sometimes the true International nature of Kodak at it's height is forgotten. There were products sold in the UK & Europe never made or marketed in the US, and Kodak Ltd (UK) had close links to many UK manufacturers of equipment and even acted as distributors in Australia, New Zealand etc (Ross lenses for example).
