Have a look at http://www.opencyclemap.org/

Android only afaik
Graphics and shifters definitely point to 83 and 600AX - however looking at first picture the chain stay has a braze on for outer cable stop which the 600AX never needed or had. Transition and last of the line?
Re: Dyna-tech MT5 Metal Matrix frame
It will not be too big at that size for you. Some nice Pace forks would go perfect with it. That frame is a one off colour scheme done for the original owner by RSP. Lovely supple ride, light as and a recommended buy.
