The "D" stands for "die-cast." The "B" is the basic pump model/generation.
Roosa invented the distributor pump in 1947. First models were sand-cast housings and called "Model A."
Model A pumps were made until 1956. Then production of the model B and D pumps began. Model B still used sand-cast housings and model D used die-cast housings.
In 1953, CAV purchased rights to copy the American "Roosa" pump and make their own version for use in the rest of the world.
For a long time there was an agreement that American equipment used Roosamaster and never CAV when sold in the USA. Obviously that deal ended at some point.
John Deere - as I recall - was the 2nd tractor company to use the Roosa rotary-distributor die-cast pump. That was on the 1960 1010. I think Hercules was the first to use it.
