From the Peeling and Van Neck 1931 BJP Almanac adverts. They were the UK distributors of Deckel and Gauthier shutters. This thread is related to the (there was a url link here which no longer exists).
These were the modern standard sizes used by Copal, Epsilon, AGI, Prontor etc.
The Ibsor was a self cocking shutter superceeded by the self cockin Press Prontor. The Gauthier Size numbersare not equivalent to the Deckel Rim set Compurs.
Recently I boughtan Ibsor on Ebay, it looked quite small and no dimensions were give, I was surprised to find it's fully Compur/Copal #1 compatible and had never been used, the f-stop piece is blank (un-engraved). There's obviously others not listed in the advert, I have a Size 3 with a Rodenstock Eurynar where the barrel diameters front and rear are identica (as above) while the new one is the same front diameter and smaller rear diameter like the Compr/Copal #1. Another is between Compr #0 and #1.
