Built over the usual (for Bill Steube) Dynamic/AMT Mabuchi FT16D, they have been rewound, epoxied (one with similar stuff as used by Dyna-Rewind) and dynamically balanced. There are small variations on these such as the placement of can screws (one of them using K&B machine screws) and sleeves over spring posts, a Dyna-Rewind/Ted Lech invention.
Few of these motors have survived, but thanks to the generosity of both Bruce Paschal and Mike Steube, the LASCM has no less than five of them now, one being in the car that Billy Steube used at the R&C Coupe race in 1967.


These were built at a time were things were simpler and probably a lot more fun, when experimentation was all and everyone had a ball building things.
Until about six years ago, no one had seen any of these since the 1960s...
