Have you ever owned or operated a part 15 AM transmitter with FCC Verificatin?
I don't really recall ever hearing about Part 15 AM Transmitter Verification before, but there it is right in FCC OET BULLETIN NO. 63 (October 1993)
http://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet63/oet63rev.pdf
Authorization Procedures for Part 15 Transmitters, is the name of the chart on page 5 which shows part 15 transmitters used for tunnel radios, campus stations, other AM carrier-current stations, perimeter protection systems, and systems operating at or below 490 kHz , ALL REQUIRE "VERIFICATION"
Shown on the list are also Leaky coaxial cable systems,they too require only "Verification", but only if "for operation exclusively in the AM broadcast band". For any other frequency then it requires "Certification"
The chart concluded with "All other Part 15 transmitters" require "Certification"
My best guess.. "Verification" is identical to "Compliance". Still it's odd because I don't recall the FCC using that term anywhere else before (in relation to part 15)
Also in the chart, doesn't apply to us, but it's interesting..
Low Power Transmitter: Devices, such as a perimeter protection systems, that must be measured at the installation site
Authorization Procedure: Verification of first three installations with resulting data
immediately used to obtain certification
This is interesting. Those carrier current systems and educational systems I've always understand had to use certified transmitters. Never heard of verification outside of full power broadcast AM/FM/TV transmitters.

No you're wrong there. They have never been required to use certified transmitters, complying with the rules was/is the sole requirements.
For the longest time most of them were home built with the entire systems being cobbled together.
... What's more, as you know, certification is exclusively a Manufacturing issue, it rarely (if ever) has any bearing whatsoever on the owner/operator of the transmitter.
Following on the heels of that 1993 OET Bulletin 63 (above) came Docket 19356 (FCC 74-113) in 1974... And that's when it chaged. https://www.worldradiohistory.com/Archive-FCC/FCC-Reports/FCC-Reports-1974-02-22_45_1.pdf
