The oil pump on the B has a check valve to keep it from losing prime however, the similar oil pump on a D12 does not seem to have a check
valve, is this true, how come ?

The ball is to build pressure behind the ball. The D 12 has the ball in the front of the camshaft to build pressure inside the camshaft so oil is under pressure for the mains and rods. The B does not use pressure inside the camshaft.

To illustrate what Dick said, I happen to be working on the same thing. The D12 uses the same block as the D14 G-149 I'm assembling. Note the Check Ball. Be sure to look it over carefully, mine was faceted from all those years doing it's job. I bought a new one (actually 10 new ones because that was the minimum quantity).

Apologize for the quality of the photo.
