Two capacitor decade boxes, with four selectors (100pF, .001 uF, .01 uF, .1 uF)
Two resistor decade boxes, with five selectors (10/100/1000/10K/100K ohms)
These have all been briefly tested, and seem to have decent precision. I didn't look under the hood to see if they're 1% components, but the values tested were pretty good.
These are also documented in this article: https://www.nutsvolts.com/magazine/article/September2016_Capacitor-Resistor-Substitution-Boxes, and were acquired from the estate of the author.
One homemade-looking “high power” resistance decade box, described as “20 Watts per decade”. Adjustable from 1 ohm to 10K. Resistors probably are not super precise (maybe 10% tolerance?). Measurements on low resistances are somewhat inaccurate. Also came from the Robert Reed estate, but not pictured in the article.
Useful for quick part substitutions when you're not sure what value part you need.
