I recently found an Eagle Lock rim cylinder in its original box with a key I didn't recognize. I have seen Eagle cylinders with the Bell style key but not with this style key. It is similar to the Schlage Everest series. The box is marked Eagle Lock Corp. , a Subsidiary of Penn Akron so I know it is probably from the 1960s or early 70s. It is the Supr Security series but also has Kno-Pic written on the box and the part # 3600. There is no patent date but it has Pat. Pending on the tail piece.
Can anyone tell me anything about this line and how long they used this key way?
Thanks
Dave
PS I'm trying to add a picture but for some reason I can't.
