I had an Academy slide rule with motor efficiencies on it in 1965, I may well still have it. On the wall in the maths room at Midhurst secondary school in the early 60's was a giant one, about 8 feet long, not exactly pocket size. After my knee heals up, I'm hoping to be able to ride the super full suspension mountain bike which I built about 12 years ago. I cannot ride with plain pedals, I have to be clipped in with SPD.

Over the early years, I went through several Unique rules, 5 and 10". Somehwere, the last 5" lies amouldering.. The plastic/paper scales came off.

I still have my father's pre war 2 10" japanese, bamboo slide rule.

My pride and joy is the 10" Faber Castell Log Log rule that i started using at Tech.

At work, the standard issue was a 10" Thornton, have one of those, as well.

In those days, we could estimate to one or two places of decimals!

And the batteries never ran out or needed recharging!

I used my fathers Faber Castell slip stick until I built my Sinclair Scientific, the RPN was something new to me but it was an entertaining machine. The trig functions were a bit wild compared to 5 figure tables but mostly close enough for jazz.
