Understood ref your own project. I hope that's going well!
Ref 8th Recce, you should know that their primary veh was the Daimler Mk.1 Armoured Car; obviously they had other vehs but that was their fighting tool.
BTW, if you ever seen (and can verify) 8th Recce insignia for a decent price, grab it.... that stuff is as scarce as 1CACR stuff and just as expensive!
