Towards the end of B-25D production, modifications that were standardised on the J model were introduced, including a revised shape Bendix top turret, larger waist windows and a similar raised tail gun sighting station. This Mitchell II (HD311) was among those transferred to the RCAF from RAF orders.

Only one of the seven operational US Marine Mitchell units is known to have used the PBJ-1H in action. This example is pictured during a test.

Among the experimental B-25H airframes was 43-4406, the NA-98X which flew with Pratt & Whitney R2800 engines during March and April 1944 before being destroyed in a crash.

North American's Kansas City plant was a major manufacturer of the Mitchell and some examples of its work are seen in this view including 43-28111, a J model destined for the Russians with earlier insignia, a B-25H-10 (43-4917) and a PBJ-1J in naval colours.

More than 800 B-25s in four models were passed to the Soviet Union under Lend-Lease arrangements, this J-30 model 44-31162 carrying markings and camouflage applied in the USA before delivery. Under the postwar NATO reporting name system, the B-25 became known as ‘Bank’.
