Bacon and Day / Burt Clark

Hi
I recently purchased a B&D 5 string made for Burt Clark.
I'm trying to put a folder of its history together.
I'm hoping that folks out there might have some high quality pictures, catalogs, articles, etc that will give me info on Mr Clark.
I've found out he was an investor in the company. I'd also like to know what years he was involved with B&D.
Any help would really be fantastic
