Oh my!
The Krays just got even better.
Pete, where do I send your cheque to?
Found the bit on spaces, page 51 where it details Arms of Service, at the bottom in Transport.
Also, re last week's game, I knew the ruile but could not recall where I'd seen it. The Artillery section on the same page confirms a towed gun is considered as an LV and LVs take two spaces each, hence a transport requires 2 spaces to take a lowed gun... such as in the Guild Legio army. I assume it's to represent crew, ammo and spare parts etc...
