George Washburn Mandolin Serial Numbers

Hello All,
I was wondering if anyone could help me determine the age of a mandolin. It was my great great grandfathers and all I know is that he purchased it in San Francisco before the big earth quake of 1906. The story goes that he survived with just the mandolin and his underwear. It is a Washburn bowlback. The sticker inside shows the serial number as 17575. It is in it's original case and has sat in my uncle's closet for some time. I've attached pictures. Any help would be greatly appreciated. I'm surprising my husband next week with it as his birthday present (after I have it cleaned, restrung and set up).
Thanks!
Cristin
