The Nye Tool Co., the tool and die firm founded by his father in 1904, was sold in 1964 to an Indiana company.
...Symington-Wayne...purchased S-K and Lectrolite in 1962.
In 1964 it also purchased NYE Tool and Die. NYE was run under Symington-Wayne ownership as "NYE Tool Company, Division of Symington Wayne Corporation".
Here's Oily's pipe cutter:

and here are a couple of others. These are all No. 2 cutters. First, what is likely a later but pre-Symington-Wayne NYE tool (note the lack of the cool, stylized "NYE" and the new recessed panel):

And here's a shot of some thread chasers post-acquisition where we can see the new logo in the familiar style of the SK-Wayne logo for mechanics tools:

I did find a newspaper article dated Oct. 2, 1963 that confirms Nye being sold to Symington Wayne. It also notes Symington Wayne as a Salisbury, Md. company - unlike previous mentions of a Fort Wayne company buying them out.
The packaging also shows the Symington-Wayne Corp. as being in Fort Wayne - a carry-over from the Wayne Pump Company days.
