Just acquired one of these babies, along with a pedal (man, does that feel good!).

I know the adjusting nut for spring tension is on the bottom...but I don't know which way does what.

I'm thinking it may be the same kind of mechanism as the early Ludwigs... with counterclockwise raisning the piston, thus increasing tension.

Any ideas?

Any other input on cleaning etc.??

I am a complete newbie on these Rogers pieces....works of art.
