Lend Lease equipment in Korean War

Maybe a little outside of the forum, but: Were there any accounts of WW II Lend Lease aircraft, like the P-63, or A-20 being encountered by UN Forces in Korea?

I don't believe so ... Soviet squadrons in the East were still equipped with P-63's, considered a good transition aircraft to the Mig-15 ... a number of P-63's were shot up in an accidental incursion into Soviet airspace by US jets. But the A-20's would have needed air superiority to be effective ... and the US had control from the get go.
Lend-Lease machine tools, stamps, presses etc. certainly would have produced ammunition for the Koreans and possibly Chinese just as they did for the North Vietnamese ...

I've read Lend Lease tube artillery sent to China ended up in North Korean hands

At least one of the T34s captured and evaluated by the US Army contained American made components.

4 September 1950 - A US Navy F4U-4B Corsair of VF-53, piloted by Ensign Edward V. Laney, shot down a Soviet Naval Aviation Douglas A-20 Box over the Yellow Sea, southeast of the Soviet-occupied Port Arthur Naval Base in China and west of the North Korean coast. Laney was one of a four-ship Combat Air Patrol from the carrier USS Valley Forge (part of Task Force 77), which was protecting US Navy air activity against North Korea not long before the Inchon landings. The A-20 was one of two belonging to the Port Arthur-based 36th Mine-Torpedo Aviation Regiment of the Red Banner Pacific Fleet, apparently sent out on an armed reconnaissance mission. A-20s had been supplied in quantity to the Soviets on Lend-Lease during World War 2, and this unit had had extensive experience during the war as torpedo bombers . The Corsairs encountered the two A-20s about 40 nautical miles from the Chinese coast. One A-20 turned back, but the other pressed on. As the Corsairs descended, the top turret gunner on the A-20 was observed to open fire. Richard E. Downs led Laney on a firing pass, and Laney hit the A-20 with his 20mm cannon. The Soviet aircraft then crashed into the sea. The US recovered the body of one Soviet crewman, later identified as that of Genaddiy Mishin, the copilot. The other two bodies, those of Senior Lt. Karpol, the aircraft commander, and Sgt. A. Makaganov, the gunner, were never found. Mishin's body was returned to the Soviets in 1956.
