Very Rare Vintage MULTIPLE OIL PROOF Spark Plug Porcelain 1920's

Here is an antique picture plug spark plug porcelain from 1920's. It is marked MULTIPLE POINT "775" OIL PROOF. The porcelain has a small chip on the tail and hairline in the glaze. The print is good.

This would be a nice replacement in a plug, make a plug or to add in a collection as is. Please check my other auctions for other spark plug porcelains.
