Do you have the whole of the cane rod or just the butt section?
B&W rods can be worth a bit... but much like anything else, they're only worth what someone will pay for them. Rods like the Hexagraph can be worth a good portion of a mortgage payment in the right condition, others are worth only a few tens of pounds and, like a second hand jaguar (only without the fuel bills), they're much better off used than sold. The DT8 and ST9 on the Reservoirfly B&W refer, as santaman said, to the line rating of the rod - use a DT (double taper) 8 weight line, or a ST (Single taper, usually called a weight forward) 9 weight. This is a bit of a broomstick of a rod it seems as I would use those weights for pike on the fly with a massive lure, or for mackerel on the fly with a team of feathers.
A complete, custom made, split cane rod could be worth a small fortune if you can prove it's provenance and it's something sought after. However, there's a lot out there which avid collectors wouldn't even use to hold the washing line up with. I would use it if it were mine, there are some lovely silk fly lines available from Thebault which would suit those lined rings well.
Sadly the shimano and the shakespear were both at the budget end even when new... they might make a tenner or so each on Evilbay.
Cheers!
