Who is/was Custom Motor Coach Works?

[BenAdams]

Hello, I recently purchased a '58 PD-4104 conversion.  It has this placard inside with the name Custom Motor Coach Works.  I'm assuming this was the company that did the conversion.  I can't find any information about them.  Has anyone heard of them or seen other busses converted by them? Photo attached.
