Norton posted:9234 simply designates its a Pittman DC040B-3. DC040Bs, of which there are 6 variations are all rated for 40V max but have different windings. After that the buyer can specify bearing, brush, and magnet type. Those are numbers and letters that follow 9234.
Here is some info, don't spend too much time here or your eyes will glaze over.

Not true. 9234 is a specific size pittman from the original co. They have moved to a new numbering system with the ownership change. Each number has a specific meaning wrt size, type of connection (wire or Terminal). There use to be some old file on the web that spelled everything out. If I remember right the 2 meant wire leads out of motor. Where a 9434 had terminals that wires connected to like the typical MTH engine of the early versions. There also are smaller length pittmans of the 9000 series. I think the MTH Premier Atlantic may have used it, or the G5. Can't remember which.
It is true the other series of numbers was necessary to know what voltage, rpm, etc... G
