Hi Mal and ODK members,

Yes, the Self-propelled did make it into production as the SP62 & SP64.
I have been told that there was only tinkering with the designs after 1965.

I also now know the GEB kirby engines lasted to 1963, and were sold alongside the
VKs that were introduced in 1960.

Note the unusual engine mount bolt in the front centre of the SP.
The cable for the stater trip release was novel, and introduced on the
SP64 Conquest in late 1963. The conquest was medium-arch, the Valiant, high-arch.
These were thoughtful designs.

Cheers
