Pink insulator plugs?

[zachmac]

So, going through the box of stuff that came with the Spider I just bought I found 7 new Lodge Golden 2hl plugs (in the boxes unwrapped) and one empty box. But no such plugs in my car. They have a unique electrode and pink insulators!

A quick Google search seems to indicate these were original equipment from SPICA for Alfa engines. Does anyone know anything more? I see sets for sale at what appear to be pretty high prices.

Found this: "Sintox, a pink ceramic that came from sintered aluminium oxide and possessed remarkable thermal, electrical and mechanical properties. As an insulator it had all the advantages of mica, yet none of its drawbacks. To the old porcelain and the other ceramics it was found immeasurably superior. Soft and pliable in the first stages of manufacture, it could be extruded, moulded and turned on a lathe as if it were metal. Fired in a very hot oven it became as hard as glass but not in the least brittle. And apart from its extraordinary inherent qualities, it brought smiles to the faces of the production engineers, for whereas the mica sheets from which the insulators had previously been wound were fragile as well as expensive, Sintox was far more easily handled. Its commercial introduction into Lodge plugs, in 1936, changed the most difficult stage in their manufacture from one that called for highly skilled labour to one in which careful control of machine processes was all that was necessary."

Do you want to sell them?

Thanks, Rick

Sure, I posted them on the Alfa board and a guy from England seems interested but no offer yet. Just pm me an email if you want pictures and make me an offer.
