I'm sure if I searched Library archives of magazines from that era I'd find adverts perhaps more listing it, but it would be a slow process. I have an Alliance Roll-Film Camera Co Ltd 110 camera (old 5x4 inch neg size roll film) made between 18 and there's nothing on the Internet remotely similar. It might have been Gauthier but who knows Too much information is lost to determine who added the focussing. Pronto and Vario shutters, However the Koilos shutter was Patented by Wilhelm Kenngott living in Paris. Several pages stamped 'Ganun & Parsons Opticians, 13 West 42d Street, New York'. Established by Carl Paul Goerz in 1886, trading in mathematical instruments began selling cameras in 1887 and producing them in 1888, renamed as Optische Anstalt C P Goerz in 1890 also produced scientific instruments and binoculars and gun sights. Includes binoculars, a folding camera and camera lenses and shutters. Goerz had offices in New York and in Paris. The Koilos shutter was made by Gauthier the main competitor to Deckel (Compound and Compur), Gauthier are better known for Ibsor, Ibso, Prontor. Includes photographs of the exterior of the factory and the mechanical and optical departments. There are various other Kodak cameras of that era with Koilos shutter and Goerz Dagor lenses of the same age. I've not double checked but one seller says that style of 1a was available 1905-1915.Д«ecause different lenses were added that's not a modification rather a variant, and perhaps one distributor decided to add the focussing. Here in the UK Kodak fitted British made lenses, and as I also pointed out Goerz themselves had an Optical works in London.

Distribution in the UK and Europe was usually by Kodak Ltd in the UK.ДЄs Dan pointed out earlier often shutters and lenses were added in the country of the final sale.

Your looking at US Eastman Kodak catalogues, the problem is your camera wasn't sold with that Dagor lens or Koilos shutter in the US.
