From the reference box # 122

#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.
