Being offered this evening is a fine looking threadless you don't see very often. This Brookfield is the embossing index [020] with the 1865 patent date. Nice big milky loogie stretching down from the top of the pinhole, looping below the wire groove and then heading north. Bright clean glass with a milky pinhole. Only issue to report is an open base edge bubble with very minor associated chipping. Pic of the bubble to follow. Embossing on the rear of the insulator is clearly legible while front dome embossing is weak but partially readable. Priced at $875 which includes shipping within Canada or the U.S.A. Personal check is the preferred method of payment. Thanks for your consideration.
