Was curious about the model numbers for flight recorder and cockpit voice recorder.
This accident report for a 727 in 1968 mentioned this equipment for that plane
Not sure what flight 305 had.

I think we talked about how these recorders had a limited span of time to record? so that when flight 305 landed in Reno, was there no interesting data to unload or do I forget something?
Interesting paper from 2021 talking about history of FDRs

This paper describes developments in flight recorder equipment and analysis
techniques from an Australian perspective. Australia was the first country to require
cockpit voice recorders (CVR’s) to be fitted to transport aircraft (1 January 1963) and
one of the first to require flight data recorders (FDR’s) to be fitted.
