I am restoring 1956 Aceca BE576 and would like to paint it in it's original colour. On the build sheet it says "Blue 605" but I have been unsuccessful in tracing this colour so far. On sanding back layers of a later white respray I uncovered some traces of a mid blue metallic paint. If anyone could let me know the paint codes of any metallic blue paints used by the factory in 1956, or their modern equivalents, I would be most grateful. You can text me on 07816862670
