VINTAGE BAMBOO FISHING POLE

I have a VINTAGE FISHING SET that I am hoping someone could give me an idea or any information on about what it might be worth, I have searched the internet and cannot come up with any info on it. I found it in my grandfather's attic.

TRIUMPH XL 500 3 PIECE BAMBOO ROD complete with everything needed to start fishing, minus the bait. Set includes 3 hooks, 1 bobber, 1 sinker, 1 leader, what appears to be a small plastic spacer, possibly for rigging slip bobber (not real sure), and fishing line (does not say what lb. it is).

Is in original packaging which has a over the should strap attached, never seen anything quite like this. If you could give any information, it would be greatly appreciated.
