There's a partial list of Orvis bamboo rods by serial number here:
Yours isn't listed, but judging from the sequence of the serial number it was built in 1957.
If you call Orvis and ask them to connect you to whoever keeps the database, they can confirm that and tell you the rest of the info about your particular rod -- how much it weighs, what line it was made for, where it was originally sold, perhaps who the builder was. I have called them to ask about bamboo rods in the past and they were very friendly and helpful. They like keeping track of their old rods and helping the current owners enjoy them.
