the tech test was administered by a higher class ham, and the general test was taken at an FCC field office (unless you lived 150 miles or more from the office, in which case the general test could be administered by another ham, and the class was called conditional instead of general).
Couple of small points:
1) From its creation in 1951 until 1954, Technician tests were given at FCC offices same as General, unless the distance or disability requirement was met.
2) The distance requirement for a Conditional was 125 miles until 1954, 75 miles from 1954 to 1964, and 175 miles after that. The distance was from "air-line" from any place where an FCC exam session was held 4 or more times a year.
3) General and Technician used the same written test until March 21, 1987. On that date, old Element 3 was split into two parts, with both parts required of General but only one for Technician. Both licenses also required the Novice written.
