I got the bike for free on fb marketplace and the owner wasnt sure what year it was. It had lots of dirt and rust on the components so i figured it was junk but I took it as a future project bike. It sat in my yard for another month or so until I finally decided to clean it up. After cleaning the bike looked pretty nice and most of the rust easily came off after being brushed with a steel brush. I was really impressed my how it looked and decided to fully restore it.
That is not a typical Maruishi serial number format. Either some characters are missing or the bicycle was contract manufactured for Maruishi. The latter was fairly common on lower end models. The combinationation of Shimano and SunTour components suggests that it has been at least partially rebuilt, which complicates matters. Still, the model designation suggests mid to late 1980s. This is a case where photos may help. Ignore the 10 post warning. Photos will be uploaded to a gallery album where members can view them.
