Dating Comoy's pipes is very often infuriating, especially when the "Comoy's" and COM stamps are at odds with one another. While I am far from expert at dating Comoy's pipes, I generally rely on the COM stamp rather than the font/format of the "Comoy's" stamp.
I should be better equipped to comment on the dating of the Kaywoodie Uncle Paul, but I really cannot offer anything in the way of an accurate date. The earliest English-made Kaywoodies appear to have been made by Civic. At some later date it seems English Kaywoodies picked up Comoy's shape numbers. Of course, Civic and Comoy's both wound up under the Oppenheimer/Cadogan umbrella.
