What is your most favorite slide rule?

[@MarkKrebs]

After this inspiration i made an elegant cream and gold Pickett 'n-34.' Common logs without the hyperbolics! ...didn't work out well.

I believe you mean "N-34-TES".

Easily one of my favourite channels and should be one of yours if you like mathematics

[@ProfessorHerning]

Thanks! I've been busy recently but hope to get some new videos up at some point.
