I've got plenty of black vans recorded, but unless it is a HX it cannot have 18V (Slate black) trim, has to be 19V (black).
If you like, send me through the ID details and i'll check it out for you. I have 8 x 2214 black HJ vans recorded, 4 of which have 19V trim. Rest are 60V or 60A. 2214 Tuxedo black was a mainstream colour from later in 1975.
