Trainspot and others,
You asked for it! (This is long!)
Here's the details for the P54D class of LIRR cars, aka the "Ping-Pongs," as built:
1-138, American Car & Foundry, Mar-Oct 1927
392-421, Standard Steel Car Co, Feb 1921
422-451, American Car & Foundry, Jun 1922-Jun 1923
462-481, American Car & Foundry, Apr 1926
As mentioned before, many (but not all) were modernized and renumbered into the 7000 series.
What follows is everything I know about these cars, courtesy of an absolutely incredible roster produced by the late Robert Emery which now resides at Stony Brook University, Stony Brook, NY:
P54D DETAILS
Exterior: Arch-roof locomotive-hauled coach; five roof ventilators; diaphragms; porthole windows in end sheets; lightweight trucks.

General: Commuter traffic on the main line from Floral Park west was extremely heavy from 1925-30. Westbound 12 car multiple-unit trains were packed by the time they got to Jamaica. The 12 car multiple-unit’s that started at Jamaica were packed after they left Forest Hills. The railroad knew traffic was going to decline abruptly from Queens Village west after the IND subway, which was under construction, opened up. Rather than buy more new multiple-unit’s, which would not be needed after a few years, the railroad converted the locomotive-hauled coaches to multiple-unit’s. P54D’s 1-137 enabled the railroad to retire the last of its wooden coaches in the summer of 1927. P54D’s 1-50, 91-99, 101-138 and 462-481 (117 cars), as of 1-1-1942, furnished base service on Patchogue-Babylon “Scoots”, Jamaica-Ronkonkoma and Long Island City-Oyster Bay trains. They weren’t normally used to Speonk and Port Jefferson. After 1946, however, they were used everywhere. 38 last unmodernized car in service.
