I have one such beast in my hand. It’s 1 3/8 across, 4 1/8 tall and on the top it says 6 MFD/928/H101. It tests open but I don’t think that’s important. I would let it go for only one million dollar (shipping included). But if you happen to have brown knobs for a Rainbow Baby Champ (2 or better 3) I might reconsider. Your deal.
P.S. You can turn off that gleam in your eyes. Jean is the french equivalent of John.
