Manual for: "laboratory 5" o'scope" IO-30 (an 11-tube oldie, ca. 1960)  Has
"Chrysler Corp" in ink, "CHRY" in purple rubber-stamp, and "CFO Hudson
Missle Plant" in pencil on front; "completed wiring 5-24-62 2:00 PM 16
hours total" penciled on page one, and pencil check-marks throughout. Good+
condx -  $10 ppd.

Solid-state 15mHz dual-trace IO-4510 o'scope manual in very good condx:
I've not found any markings other than "$20.00" on the front, and four
small words in red ink on the bedsheet-sized main schematic. (this was not
a kit o'scope)  $20 ppd.

Yo's free to make offers - I really have little idea what these are worth!   e
