The yellow slide rule is a Pickett Simplex Trig N902-ES (ver.1) with K, A, B, T, S, CI, C, D & L scales. Fortunately, it has instructions printed on the back so that I don't have to find a manual if I need to use it. I picked it up at Goodwill for a buck.

The clear ruler thingy is one of those "as seen on TV" jobbers my mom picked up many years ago. It's got several geometry & trigonometry formulas on it.

I forgot the E6-B or the CPU-26A/P and the plotter along with the sectional.

Now, if only I had a sextant.....
