Tech: Williams Pyramid Shuffle Bowler

I am starting a resoration of a Williams Pyramid shuffle bowler and
the cabinet needs to be repainted due to flaking and fading. I am
transfering the design onto vellum to make stencils from right now.
The problem I am having is the colors are very faded and yellowed and
I can't really find a clean spot to color match. Does anyone know the
correct Pantone colors that were used on these? There is a white(ish)
base, a yellow layer, and a teal(ish). Any suggestions for commonly
used colors by williams would be appreciated. Oh, score card scans
would be great as well.
