Hello Don,
I´m not specialist in electronics and 1:24 slot, so that I might fail in what is going to say, but my hypothesis is:
the first owner used a transformer 6V with the reference H19 of Strombecker'60. which was the second transformer marketed by Strombecker ( or first when 1:32 to do Strombecker scale cars ) .
That transformer was designed to run car carrying Japanese motors 3.5 V Kako, that were included in the first 1:24 of Strombecker cars 1959/60 and the budget versions of the Jaguar D 1:32 included in the circuits 312 and 313 (by the way the car is not the first version of that model and those circuits are not the first as some sources say ... but that's another story ...).
The issue is Kako 3.5 V motor is a low volume performance and a very complicated due largely to its side magnets, as a consequence it is very difficult to make mechanical changes.
I think the first owner of a material Merit / Strombecker 1959 or 1960 (references static kits Mercedes and Maserati GP GP and D43 D41, respectively), in turn transformer 1960 and commented at some point change from 1963 standart engine mechanics using open Strombecker 12V ( really built for Strombecker by Igarashi of Japan).
The new chassis, motors etc give more guidance and performance but the first owner still has the same old transformer ! .
I apologize because my knowledge of electronics are not adequate, but I think the capacitors appear to have a transformer 6V with 12V powered cars.
There were a few years following the sale of Strombecker hands of Strombeck-Becker Dowst in which there were no developments at 1:24.
During this time, fans of this scale and the mark, had no solution to customize their own cars with original Strombecker parts, then they did these things.
