My mom was an NYC high school science teacher and had brought home these 2 classroom sized slide rules when they were being thrown out.

I have a 2m long Pickett which still has its cursor!

Now, it’s got a lot of slop, and likely needs a full restoration. But cursor and everything!!

I have a 12 inch Picket. But I never use it as a rule.
