NOTE: Sid Lethbridge 2024 - ...catalogue cut from an 1897 Pitkin & Brooks wholesale catalogue. Pitkin & Brooks generally used the OMN (original manufacturer's name/number) which is sometimes very helpful. My suspicion is that this was made by the Eagle Glass & Manufacturing Co. of Wellsburg, WV. At any rate, we now have an OMN of No. 110 and a circa date of 1897 that we can be comfortable with and a guess at the maker.
