My grandfather passed a fly pole down to me. It is a Heddon 9 footer. The rod has these markings above the cork: "#10-9'-2 1/2 F-HCH or D"
What do these mean? Other than the 9', I'm pretty much lost. I can assure you its no 10 weight either

It has an extra, possibly different, tip. Anyway of telling how old this pole is?
I could take a pic of the handle if you want.
