Data from William Bay, Danmarks Damplokomotiver (1977). Works numbers from [] . According to Jens Vesterdahl's Danish Steam Locomotives site -- [
] (9 July 2003) -- locomotives were added to this class from 1898-1923, plus another 15 in 1949. Over that time, engines were supplied by Frichs (Denmark); Hanomag, Borsig, Henschel, Hnttemeier -- all German builders; Tubize (Belgium); Breda and Saronno (Italy).

Beginning not long after the last deliveries of the saturated-boiler G (III)s (Locobase 4012) , the DSB superheated 20 of the large class of 6-coupled freighters. 3 were modified in 1913, 4 in 1914, 2 in 1915, 1 in 1916, 3 in 1917. After a break of 6 years, 4 more were superheated in 1923 and 1 more in 1924. Five more of the slightly earlier G (II)s (Locobase 4006)were also superheated in the late 1920s -- 1 in 1926, 2 in 1927, 1 in 1929, and the last in 1932. The result was a bigger boiler pressed to a greater degree.
