Here is the engine from the next car.
Much simpler 4 cylinder and a much older car.

Do I see some lozenge camouflage from a WW1 aircraft?

Rusting looks good.

YES like all my models out of my head - or its more like, its the first out of the scrap box went onto the model hohoho

Do the letters/markings have any meaning?

Subtle coat of rust (yes Zak subtle from me hohoho) next job coat of matt varnish, expect it will go silver but heyho its been fun making it.

Looking very plush. Very nice work Dave.

Mirror and support installed.

I reckon a car showroom diorama would look great.
Very nice work.

Looking like it should be in the show room - with people keeping it polished and ready for sale
