Re: old bamboo rod
HDH indicates a 6 wt DT line...although with bamboo - there can be some variance...try a 5 wt and even a 6wt WF line to see which one works best. I don't recognize the name...perhaps it is the owner.
As for the set in the tip...it can be straightened...but if you have no experience with bamboo I would not try it...better to find someone who has fished bamboo alot or better still someone who makes or restores bamboo...they can also give you a sense of the value of the rod...and if it is worth fixing...if the set is the only problem and the ferrules and reel seat are good and tight there is no reason you can't fish the rod. 8 1/2 ft indicates it is a trout rod.....the 9 ft and longer rods generally are for steelhead, etc.
there is a bamboo forum..... classic fly rod forum...on the web...don't have there address though...they might be able to help you out
