Here's a solo-photo of the slightly darker HG smooth base that is in the following photograph (the one on the left). Note that it is a tad shorter than the one on the right and has pinhole threads that nearly come out the top of its crown! FYI...as a side note...HG Co. and other earlier Hemingray insulators (pre-circa 1920) have been not-so-commonly found here in New England. That's been my experience while hunting in the wild during the past 40 years. Apparently Brookfield had the market predominantly cornered up here in the Northeast until they went out of business. That would make sense on account of less of a freight expense from most other glass insulator makers. After Brookfield's demise it was the Hemingray (Made In USA lettered) versions, Lynchburg's, Gayner's, Whitall Tatum's and so forth that we have found in this neck of the woods that apparently gained the popularity among utility users from the mid 1920s. My point is that I and other Northeastern US collectors really can appreciate these early Hemingrays because not only for their beauty but scarcity no matter what color.
