Eagle Supr Security IRS Padlock

[Scott Klemm]

A very interesting lock and one I previously had not seen! What especially caught my attention was the key that almost looks like 2 keys fused together - one pin tumbler type and the other a Bell type with a wavy groove. It reminded me of a key type associated with a watchman's signal system made by Dudley. Its so-called tour key has a lock fitted within its stem that fits into another key within the box. This box key resembles the IRS padlock key in that it also looks like 2 keys fused together. It even has a groove down the center, but is straight rather than wavy. I have posted three pictures. Incidentally, does anyone have information about Dudley? All I have been able to find out is that it was originally located in Chicago and then moved to Canada. The company apparently was acquired by Master.
