Question
since my piano is outside of your expertise and I have looked almost every where else online that I could think of could you give me an idea of where else I could go to look up this serial number such as a book or maybe a website that does extensive research at a cost?

Answer
I can only answer from my experience with brass instrument manufacturers.  Generally, the companies used the serial numbers just to track the instrument through production, and didn't intend for them be a historical record.  Many of the serial number lists that exist were collected by interested individuals that re-compiled them into a rough way of dating.  Most serial number lists are not drawn from company records.  

Additionall, when companies went out of business, their records were generally destroyed.
