Details
Embossing: (f) Brookfield (b) No Leak D./Patented
These are found in shades of aqua, green aqua and near green. Only a small number have been found with notable amounts of bubbles or inclusions. The one on the right is an unusual example.
This is a two-piece design with a glass insert. As described in the patent info, the glass insert was designed to fit into the underside of the insulator to maintain a dry and clean zone within the inner skirt area, thus the name "No Leak". This, of course, was for the prevention of current leakage due to wet weather or the build up of debris, such as spider webs. Due to the fragile nature of the insert, there are many Brookfield No Leaks in the hobby that lack a matching insert. I'll stretch my neck out and say at least half, maybe more, of the No Leaks known are "insert-less", with some inserts having been repaired. PicturePoster #178151641

There was a report in a 1970 issue of Crown Jewels that a rubber gasket or washer was found with a No Leak and insert. Can anyone verify that a washer was used?
