This page would consist of charts with data on the machines and links to the photographs. It could be split as follows:

Early Line (I can't recall what the correct designation is here)

Silent Speed


Consolidated Model

Adding Machines

Imports (Diehl and Hamann)

The relevant data that would be in the chart might be:

Model number (with link to photo)


cycle speed


years in production

link to age -vs- serial number
