I'll take a guess; FL 108 should denote a rod built on a 2 piece blank 108" long, yours could have been extended a couple of inches by the builder, or the 108 could have been nominal rather than actual length. The Fenwick wiki page https://wiki.fiberglassflyrodders.com/wiki/Fenwick only shows one 9' production rod on the Grizzly blanks #335 as a 9wt., so I'd guess yours might be the same blank, 9' 9wt. custom built.
The main wiki page https://wiki.fiberglassflyrodders.com/wiki/Main_Page has links to information on most rod makers in the left side bar, you can try to find your Shakespeare and Phillipson on their pages. There's not much graphite info on this site
There is also a Search button near the top right that will let you find many past posts, enter you rod info and find what was said about it previously.
