Greene and Greene router bit source question

[Brian in sunny FL]

My mistake, that bit looks like a "fingernail" bit or half bullnose or whatever others may call it.

That's not a Whiteside unless it was done as a custom bit for somebody.

The coloring for some reason made me think Amana and they have bullnose bits with the bearing guide.

You are right.  It is a custom.  I found the bit for sale on the Ng website.
Thank you,
