grand action in an upright

[Mark Schecter]

Hi, Cy.

Thanks for the links. The Steingraber seems like it could be 
interesting, but it's difficult to decipher from the picture exactly how 
the supplementary system functions. Even the pdf brochure is vague. It 
would be interesting to see really good diagrams or photographs that 
were _intended_ to reveal the design.

On the other hand, I looked at the picture of the Sauter action, and I 
don't see anything different about it - it looks completely ordinary. 
What am I missing?
