Head badge is riveted, I would say the rivets are brass; and very small. They look just like the ones on the International that we bought new back in 1977. I think it has been repainted because the paint seems to chip off in two layers. I will know more when I strip the frame. The paint thickness would indicate it has been painted two times. But...there is not a NISHIKI decal on any tube. There are two decals on the seat tube. At top is a leaf crest with "double butted" and then two lines in the decal of which all that is left is ****unume. At the bottom of the tube is a decal that says "made in japan". (japan is in script, but "made in" is in block lettering. The Sugino crank says 47-5 and 171, which seems to date the crank to 1971. Can you point me to the instructions for posting a picture? I thought I knew how but it's not working.
