Thanks! Yes 2 of the air cleaners. They are from a Hudson Twin H set up. The plug wires are 7mm cloth, with a clear coating to keep them from fraying. I got them from:
And who was to know that just a couple of months later I'd get a good look at a Hudson with the 'Twin H-Power' setup?
This is on a very nice car recently imported here. While Hudsons sold in Australia until the mid-fifties, numbers were dwindling and they certainly didn't offer such options in our market.
