Well, Wes Jordan built rods are pretty highly thought of in the collector market, as long as Orvis has verified that he was, in fact, the builder. They can do this pretty easily, and I would check it out before I bought the rod.
I have to say that 8wt bamboo fly rods are not very popular. It was probably a salmon or steelhead rod back in the day, but I have a feeling that the rod might feel a little like a big wet noodle. If its just for decoration, it won't matter.
IMHO, rather than pay good money for a rod that you probably won't use, and may not enjoy casting, I'd buy a reasonably priced bamboo fly rod from a current builder, in a weight, action, and length that you might want to use one day. Rods in 7 1/2' 4wt or 8' 5wt, are really popular for trout fishing. Bamboo rods are pretty to look at, but they are not delicate, they're build very tough and with reasonable care can be fished for many many years.
I could give you a few names of good current bamboo fly rod makers that sell at or under the $1000 mark. The quality, action, and workmanship are at least as nice as the older rods, and in most cases, even better.
