All this searching around in that old speed shop attic got me thinking about what the heck I have forgotten about in my own house! I think I remember buying this way back in the 1970's. It has a 1972 date code on the box. Anyone know who made these? It looks very "Sun" like, especially the way the redline mechanism works. It took the cup off but there was no logo or any info inside other than a little sticker that instructs you which resistor leads to cut to make it work on a 4 or 6 cylinder engine.
