For another oddity, I believe there was a Ju-52/3m that had a DB601 in the nose position for flight testing the engine.

Also remember that originally the Ju 52 was a single-engined design.

A former German Junkers Ju 52/3m at Howard Field, Panama Canal Zone, in late 1942, in service with the USAAF 20th Transportation Squadron, Sixth Air Force. The aircraft was designated as a C-79 and given the serial 42-52883 while in USAAF service.  This Ju 52/3m ge (c/n J5283) had originally been D-AENF. On 1 April 1937, it was transferred to Lufthansa Südamerika for Andes service and named "Aconcagua". It was again transferred to the Brazilian airline Sindicato Condor as PP-CBA on 11 September 1939 and then to Lufthansa Sucursal Peru as OA-HHD on 29 November 1940. Syndicato Condor then leased it to Sociedad Ecuatoriana de Transportes Aereos (SEDTA) on 25 April 1941, where it was registered as HC-SAD. It was confiscated by Peruvian government on 5 September 1941 and acquired by the USAAF as war prize on 13 May 1942. The aircraft was refitted with Pratt & Whitney R-1690 engines with modified cowlings and 3-bladed propellers. The air-brakes were replaced with hydraulic brakes, a tail wheel was installed instead of the original skid. All instruments and the radio were replaced with U.S. equipment. In December 1943, it was turned over to the U.S. Public Roads Administration in Costa Rica in as TI-60. Further records show that the aircraft was condemned on 20 December 1943 or 7 December 1944.

MPC's box art for the Spanish Civil War variant was a rabbit hole I never went down.

Because nothing says Guernica like a Tante Ju.

First a couple of oddities:

I suspect that the radial-engined one is a P&W Wasp-powered Ju 52/3msai. The cowlings look very similar to those of SE-AFD. The cowlings of South Africa Airways' Ju 52/3msai ZS-AJC also look similar.

On the C-79, many thanks for the engine-change detail - hadn't seen mention of the R-1690s before. The replacement cowlings are a puzzle. What was their source? I wondered about the 20th operated Douglas C-33 fleet. But photos from 1943 show a Douglas B-18A with similar 'flat top' cowlings in Panama. But, I guess, these cowling could have come off a host of Douglas products of the time - B-18, DC-2, or early DC-3.

BTW, about that Wikipedia caption: Peru didn't seize the aircraft. It was the Ecuadorian government that confiscated HC-SAD from the Sociedad Ecuatoriana de Transportes Aéreos in 1941 (around the same time that SEDTA's German employees were deported). Then, both HC-SAD 'Aconcagua' (wk.nr. 5283) and HC-SAE 'Azuay' were taken on by Ecuador's air force (retaining those names). After 'Azuay' (wk.nr 5109) was written off (engine failure on take-off from Quito), 'Aconcagua' was transferred to the USAF as 42-52883 (dates varying between September 1941 and May 1942).

Does anyone have access to the American Aviation Historical Society Journal, Volumes 36-37, Fall 1992? Dan Hagedorn's article 'The Trek of the Aconcagua' would probably fill in the gaps in the C-79 story.

The one-off Ju 52/3mba was powered by Hispano-Suiza V-12s - a 750 hp HS 12Mb in the nose and  570 hp HS 12Nbs on the wings.

This aircraft was built for Prince Bibescu, [1] then-head of the FAI (replacing a Ford 5-AT-C Trimotor which crashed after a collision with a vulture over Bhabua, India in April 1931). CV-FAI  was c/n 4016, later re-registered as YR-ABF in JUne 1937 when it went to LARES (Liniile Aeriene Române Exploatate de Stat). It was written off in a crash at 'Bazargio-Dobruja' on 23 May 1940.

__________________________________________

[1] A few sources lists George Valentin, Prince Bibescu as 'Gheorghe' (his grandfather's name). The CV- registration is a minor puzzle for a 1931 aircraft (most sources say Romania switched to YR- prefixes in 1929). The CV-FAI registration was inherited from that crashed Ford Trimotor.

I suspect that the radial-engined one is a P&W Wasp-powered Ju 52/3msai. The cowlings look very similar to those of SE-AFD. The cowlings of South Africa Airways' Ju 52/3msai ZS-AJC also look similar.

You have a point there:
