End of 2005 I ran on Ebay into a old slide rule (A Unique
Universal 1). Because I used a slide rule when I was still at high school, it
raised some old memories and I bought it. The slide rule virus bit me an I
started buying more and more. Soon I found out that there were too many different
slide rules to chose from and that I had to make a choice. Rather randomly I chose to
start collecting Faber-Castell slide rules.
This website documents the slide rules I have collected
and the information that I have gathered. I currently own 233 slide rules. Part
of my slide rule collection is shown on this website. |
