Presentation
(1948 - Early 1980s)
This model is similar to the Original Deluxe but with two important differences. It has a gold plated top plate and, until sometime in the early 1980s (the company was moved to Maine in 1979), it had a LaHiff adjustable mainspring. This adjustment allowed the spring to be slid in and out by the operator to change the rate of vibration and thereby the key's speed. The Presentation, as a separate model, therefore ended with the removal of the LaHiff adjustment. Today, the Original Presentation is basically an Original Deluxe model with a gold plated brass top plate and is not a distinct model like the earlier Presentation. |
