Does anyone recognize what brand bike this head badge decal is/was used for? It came off of a Mtn. bike I picked up today at Goodwill. The only other labels on the bike are "Made in Taiwan" and a double-butted, Tange Cro-Moly decal. I looks like it could be a decent bike under the teal paint job that probably covered the original paint. Bike looks like it's from mid to late 80's, possibly early 90's. It's an 18 speed with Shimano shifting components, Dia-Compe brakes, Sakae alloy cranks/chainwheels and alloy rims.

Any help would be appreciated!
