Back in 1983/4ish I rode a cKuwahara like this that I'd like to replicate:

I've been told it's a Supernova or Non-looptail Nova. However, I'm getting a bit confused.
This is STFC's Supernova - note the rear dropouts - they're nothing like my old Kuwie. There's a triangular shape to them whereas mine was square:

I read somewhere that many of the Tange frames of the day (ie Raleigh & Kuwahara) were the same, but with different serial numbers. In fact the retro Raleigh Aero Burner frame looks identical to my old Kuwie in the pic. I can't recall if my old bike had 'K' or 'Kuwahara' stamped on the dropouts or brake bridge. In fact it looks almost as if the brake bridge was round & not flat such as the Laserlite.
The Kuwahara Survivor had a lip on the bottom of the dropouts like this:
