Looking to ID this old Fuji.
 

This lovely bike was left at my parent's house and no one came back for or claimed it and I can't figure out what model it is. I've looked at Fuji Bicycle Serial Number Formats - 1971 through 1991 with no luck. It has a few different serial numbers on it MN02121 and PA2303 are on the bottom of the bracket shell. Then on the seat tube is M8809305, the second 8 might be a B.

I just want to know approximately what year it is and what model.

Thanks for any help.

Look on the back of the crank arms for a 2 digit date code.

Pictures, or minimally, a thorough descriptions would be helpful.

Color? Number of speeds? and decals? any equipment with model or manufacturer? Wheel and tire size?

Post up some pics of your bike. Or post them to a free site like Flickr and post the link. We can take it from there.
