Welcome to
Jay's Slide Rules

After 25 + years of collecting slide rules, antique mechanical calculators, flight computers and other antique devices, I have decided to sell off my collection.

One thing I have observed while searching for slide rules, people will collect anything.
This observation resulted in me coining the phrase:

" If there is anything to collect, somebody will collect it. "
