An amazing all original 3Rensho Katana

Check out the paint and panographed parts..

This is a readers submission and was a basement find where the bike sat untouched for years..It's obviously seen some wear but the bike is 100% original.  The bike was a special build for a bike show.. 

The Sante cranks appear to be prototypes.  

I'd put the year of the bike to be around 1987

Thanks to Stan T for the submission
