Inliners International Forums General Discussion Engines modern paint code for 216 motor

I've been searching the archives both here and several other sites for modern paint code for the so-called Chevrolet blue-gray engine paint used from the late 30s up to around 1954.

Does anyone have a PPG, Dupont, Ditzler or equivelent code?

I know I can order paint from Bill Hirsch or Jim Carter, but would like to get an actual modern code.

Thanks,
Steve
