yes correct small 16.5 frame.org. had a well used shimano 600 rear changer & a xce suntour front changer,girvin flex stem.my thinking is that the sticker could have not been from Miyata since I had no info of past ownership.to finish the rebuild I played it safe & went with m730 bits since the front brakes were m732,hubs m730,BB dated 1991 may have been replaced from org..a mystery for now but completed.
