I could be wrongggguuueee,
but that white 'tator is the same one that's in my LTC Paul's latter day Tag which operates with the short fast stroke.
I thought only the green 'tators went long and slow. Is that what you're talkin' about, Malcolm?
The stroke and finning are different, but it is the same size as the green, and perhaps, they're interchangeable.
Or is this simply a re-make of the vintage green in a new color?
