RE: Cover Girl HP-65
A correction: My super deluxe Pickett model N4-ES slide rule actually has 34 scales, not 23. However, several of the 34 scales (16 on one side, 18 on the other) are duplicated or wrapped, so the number of unique scales is subject to debate.

That's twelve full inches of sweet aluminum log-log goodness, copyright 1959. It's the most powerful general purpose straight rule Pickett ever made.

Alas, my eyesight now demands a strong magnifier and a bright light to read any of the markings. I would be better off with one of those two meter demonstration slide rules which once hung on the walls of high school algebra classrooms.

This is actually my second Pickett. My first was a much simpler, single sided plastic model with nine scales, a present my dad gave me for my tenth birthday. I've still got it.
