#122 - Vintage slide rules and dials from the 40's, 50's and 60's.
I realised after finding the Nuclear dials and slide collection the other day, that I had only ever posted a few of my own dials and slides.
So here are a few more, from Dial-o-metric to Trigonomotry ratios, there's almost a dial for every occassion!
You can see the rest of my collection here
or have a rummage for the others in our reference box
