Klein Rascal tubing

[Elfman]

Does anyone know if the tubing used on 1990-94 Klein Rascal is the same diameter as that used on the Attitude? I know the headtube was smaller (for 1" steerer), and I know the tubes were single butted and not double butted, with exception to the headtube which was double. I seem to recall that the Adroit's downtube was 2" and the Attitude was 1 7/8", but what was the Rascal's size? Thanks for any info.
