This is a CD 133 (020) F-HEMINGRAY/No 20 R-PATENT MAY 2 1893 in aqua. You see a lot of CD 164 Hemingray No 20's, but very few of these. This is a must for any true Hemingray collector. Except for partial damage to 5 or 6 sharp drip points, this insulator is vnm. Sorry, this insulator has found a new home!
