All bikes really break down into three things........ Frame, wheels, & components. In order to get the attention of collectors you need to provide the manufacturer name of all three. Looks like you got some pretty interesting stuff. If it's equipped with Suntour components it's more than likely Made in Japan. Frame is probably either Tange or Ishiwata. Get a luggage scale & weigh the bike. If it's under 24 or 25 pounds you got a nice one. Down around 21 or so you got a really nice & valuable one. Value on vintage Japanese bikes is usually around 1/2 the value of equivalent vintage Italian bikes.
