Most American doubles manufactured before 1950 had a floating rib to allow heat expansion. Many of the guns manufactured post 1950 have a solid rib and make no allowance for expansion. A Rizzini O/U I handled this AM is a good example of a solid ribbed gun.

Yes. Some did, however A Parker Vent Rib is not floating. The entire thing is soldered together in separate pieces.
