I’m assuming it’s original due to the lug tracing, but there is a thin layer of white between the red and the chrome. Also I was wrong about the decals; there is a single, tiny gold decal at the bottom of the seat tube that says “SEKINE CANADA”, which would have me believe the paint is original to the factory at least.
But this is also strange, because the serial (Y9 3800) would have me believe it was built in Japan.
I'm starting to wonder if this was a custom order frameset.
Based on the serial number the frame manufacture date is 1974 September. This date means the frame was made in Japan because the Sekine Canada facility did not begin manufacturing frames until 1976.
From the 1975 Sekine Canada catalogue the SHS 271 model came with burnt red colour.
Edit: The fork on your Sekine does not have a chrome cap on the crown. This is uncommon.
randyjawa bicycle above appears to be an SHS 271.
