[AJD] Dating this 55H plow

The "Plow Mania" by Richard Hain indicated that the "H" in the 55 plow indicates hydraulic version and they came after the war and we discontinued about the same time as the two cylinders. My plow has spoke wheels with rubber tires. The number on the beam says "55A-B-H". The trademark on the back of the moldboards is the 1937 trademark. The Trademark changed in 1950 so I assume it is after 43 and before 50. Can you shed any light on this?
