Description

#1529       CD 120       B     H. BROOKE'S  PAT     AUG 14 1883.          Brooke's blue.

Produced using a threading mandrel which was covered in a patent issued on August 14, 1883.  This same threading technique was also used in the production of various insulators with either "Brooke's" or "Patent Applied For" marking on CD 120, 125, 132, 133.1 and the CD 109 and 135 Chicago Insulator Company items.

Typically found with fair amounts of damage.  This one has some blemishes, but a better appearance than many. Has a couple wire rub marks in the groove and associated two flakes the size of a match head.  Two other ridge flakes that are a little larger than a match head.  Three thin base flakes are slightly larger than a match head.  The description makes it sound worse than it actually appears.

Displays well from both sides (especially the front), as the blemishes are all small.
