Good memory, Steve!  My original Lehman (long since gone, donated to Yamato
High School in Japan) used a knife-edge which required perfect adjustment
in order for the entire knife edge to contact the base.  this adjustment
was made via the turnbuckle in the middle of the suspension wire.  The
other newer designs are far superior but it worked well for a long time.

Regards, Ted
