Any ideas what this is?

I found this while cleaning out my father-in-law's old storage barn. It's a bamboo pole in pretty good overall condition, but I have never seen one with line guides or a reel like this. The reel is only to store line on -- the handle slides out to allow line to be spooled off and then slides back to lock it. The rod is in two sections with a threaded connector. Overall, it's 12' long. It has several guides like the one in front of the reel and the 90 degree guide at the tip
