Hello Oleg, I have a Graham TVR1 engine too and was thinking of painting the aluminum parts black, just as you did. What paint did you use?
And did you cut out the cylinder base plate? Because the one I have is rectangular in shape. Yours looks much better.
A very nice engine!

Sorry I can't help with boiler size.
