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.
I am skeptical that they're both SHS's. Randy's bike is the burnt red mentioned in the catalogue, mine isn't, its a completely different matte red. Mine also has yellow lug lining, and is fully chromed, unlike the SHS in the catalogue. Mine is also lacking all of the decals common to Sekine's of all ages. Yet, the bike probably came out of the factory this way, due to the single sekine decal on the frame (aside from the head badge).
I'm starting to think it was a one off produced for some unknown reason. Whatever it is, I've been looking and haven't seen another like it.
