the ones stamped with the Kuwahara K on the dropouts...do they actually exist ? thought id try and find some if they do 
The K stamped ones are Kuwahara not tange. They are not TRX either.
The K stamped even though they have the same holes as the TRX have a different loading point. They are like a front loading fork with a front or angled loading dropout.
At least these are the only one's i have seen.
I think they came on the 2nd edition Nova, the KZ4 Laserlite and the Survivor.
I had a supernova, these came Kuwahara Stamped, the forks on them look like round tubed TRX but were not stamped with the K like the frame was on the rear dropouts with kuwahara on the brake bridge, seat tube and bb shell.
The second edition nova on jamies site in the old articles segment you can make out the angled loading forks on the pic of the bike in white, these were the K stamped ones. (september 84 non looptail)
