Based on the livery, the Bauer is circa 1986-1987. I'm surprised it has Schraeder valves, which generally indicates 27" wheels. Also, the rear axle is nutted. The brakes and derailleurs appear to be Shimano entry level units, either LIght Action or Z-series. Most important unknown affecting the value is the tubeset. Given the components and era it could be anything from hi-tensile steel to a seamed double butted CrMo main triangle. Most Bauer from this era are manufactured by Maruishi.
