Dive Flap Drive - only P-38J-25/L ?

[ClinA-78]

Hello,

Is the Dive Flap system fit FROM P-38J-25 and -L versions?
BUT :
Was this device retrofit to earlier versions ?

Dataplate ("Dive Flap Drive" Assem. No. 404630) was found on a P-38 crashsite during the Bulge, between Marche en Famenne and Rendeux. No date, no info.

Is any possibility with the s/n on that part ("3776") to be linked to a particular aircraft s/n ?

Best for 2026 ! -H-
