Table 1 of the manual you mention, in the connectors section, lists both
types of connectors.

A few years ago I bought an Army SCR-274-N two-transmitter FT-226 rack
and a three-receiver FT-220 rack and a BC-456 that had been removed from
an aircraft with most of the connectors still attached, with about six
inches of the wiring harness still connected to each.  All the
connecters were the "open back" (no ferrule) PL-xxx-A type connectors,
and the cable harness was unjacketed laced-up individual wires.

My manual for the ATA/ARA (June 1940) specifies only the closed-back
connectors, and jacketed cables.

My manual for the SCR-274-N (TO 08-10-50, Feb. 1943) specifies either
open-back or closed-back connectors.

My manual for HF/MF AN/ARC-5 (AN 16-30ARC5-2, Dec. 1954) specifies in
Table 1 either open-back or closed back connectors, though the diagrams
showing cable construction show only the jacketed cable, closed-back
connectors.

Dave Stinson used to have a good depiction of a SCR-274-N receiver open
wiring harness at http://www.arc5.com, but last time I checked that URL
failed.
