Data from Skice I Glavni Podatci Lokomotiva (Zagreb: Zelieznicko Transporno Poduzece, 1955), p. 11; and A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot, Devonshire: David & Charles, 1966), pp. 130. Works numbers were 1-14 in 1938, 15-17 in 1940, and 18-22 in 1941.
Locobase 1539 describes the original MAV designed and built Class 22 local passenger tank locomotives. Budapest delivered thirteen--MAV works numbers 5123-5135-- in 1933-1934 as the Serbian-Herzogivina railways 414 class.
The JZ's 1955 diagram shows the 22 locomotives built in Yugoslavia in 1938-1941. They were the first locomotives to be built in the South Slav confederation. Most operated on the Croatian HDZ before being incorporated into the JDZ after World War II.
Two significant changes were the slight reduction in external tube diameters and tubes and flues lengthened by 200 mm (7.9") each. Yugoslav designers replaced the MAV's boiler toppings (three separate domes for steam and sanders) with a merged sander under a single casing between the safety valve stand in front of the cab and the steam dome just behind the chimney. The last five used Lentz poppet valve gear in place of the Heusinger constant-lead setup. Speed limit rose to 80 kph (50 mph).
