I can add a few.
Ithaca makes the Model 37 pump on the design of the Remington 17, which was a Browning design. There is a Stevens pump of Browning design, but I do not remember the model number.
Browning designed the basic Superposed, but, as with the HP, did not live to see it in production. His son, Val, designed the Double Automatic.
The Winchester 1893, predecessor to the '97 and the 1901 successor to the '87, were Browning guns.
Lots of non-FN/Browning versions of the A5, from Remington, Savage, and other foreign copies sold under the names of Herters and Charles Daly.
