According to Turner & Nowarra, five "Ju-52/1m"s were built:
- Ju-52ba c/n 4001 D-1974 (first flight 13 Oct 1930), 800 hp Junkers L88
-- became Ju-52be with 755 hp BMW VIIau
- Ju-52d ? c/n 4002, 800 hp Junkers L88
-- possibly re-engined as Ju-52do, 750 hp Junkers Jumo 204 diesel
- Ju-52di ? c/n 4003 D-2133, 750 hp A-S Leopard radial
- Ju-52ce c/n 4004 D-2317/SE-ADM, 755 hp BMW VIIau
- Ju-52cai c/n 4005 D-2356, 750 hp BMW IXu
- Ju-52cao c/n 4006 CF-ARM, BMW VIIa then 825 hp RR Buzzard
Airframes differed slightly from the later Ju-52/3m. The Ju-52's vertical tail was smaller and horn-balanced and the Ju-52di was flown for a time with a shortened rear fuselage.
