I located and purchased a 1964 250 V8 with LHD and manual Transmission. Ever sweet.
I’m in the process of restoring it and repainting it. I like the thought of silver for the top half, with med/dark grey for the lower half. The interior is dark red. Phil
Your car your decision 
could work from memory that would have been a colour scheme Daimler might have used.
I don’t think there were many Manual V8s made, is it original or converted?
any new updates on the restoration you’re doing?
