I can't recall how much I paid for my Post Versatrig^© in 1966. But making $2.25/hr (min wage) as a Draftsmen Trainee ('apprentice') I know it was a good part of my weekly take home pay.

I still have it, the Instruction Manual and Case too. All pristine condition. Turned out the simpler one sided, Post^© model 1447 (Bamboo body) I had was adequate for most of my calcs then. Which btw is also in Pristine condition, its right in front of me now ;)

Both are prolly worth a pretty penny now.

Prolly why I bought an Acumath...think I got it in 1965, mebbe earlier. Still sits next to the computer 'just in case'...in it's leather 'case' sleeve...tho' I'd be hard pressed to find the instructions.
