Jon, I don't know whether the CAV DEL in either long or short armature form has any significant advantages over the later C35A/M, other than being a nicer engineering answer due to the better bearings. The CAV is a four pole machine, the Lucas is a two pole but I can't see any practical advantages there.
Most of the internal resistances on CAV DEL dynamos are open circuit; I usually wire an external 7.5 or 10 ohm wire wound ceramic resistor between F and D to give 1/2 charge.
I've got a DEL short armature on my '29 RK saloon and it works very well at 7.5A/3A charge rate and has done for a few years now.
