53cm SHOGUN 500 12 Speed Road Bike ~5'4"-5'7"

Shogun was not a brand it was decal or what is also known as a importer brand which means some company made it and then the importer slapped a name on it like Nishiki and Centurion, and now Schwinn and Cannondale just to list a few. That does not mean it's a crappy bike though! Tange Champion 2 was among the best touring frames (though the 500 was a sport geometry which means the frame was in between a tight geometry of a race frame and a stretched out geometry of a touring frame) on the market at the time, but the cost to buy the tubesets were less expensive then other touring tubesets so Tange had a bad rep till later when people caught on that it was good stuff.
Thanks for the info, I cleaned it up some yesterday and it looks a lot better. The stem shifters appear to be original to the bike and although there are no markings left I have ID'd the derailleurs as early Deore which would be correct. Still up in the air on what I'm going to do with it but switching wheels is not part of the plan. I'll either detail it and replace what needs replaced or strip it and keep the bits I want and Ebay the rest. I took a short spin on it which was quite a sight as I'm 6'1-1/2" and it rides pretty nice as is. If it was my size it would probably be a keeper. Seems a shame to take it apart and scatter it but it may become a donor bike if I find a suitable frame.
