Data from Krupp im Dienst der Dampflokomotive (Essen, Germany: 1940), p 88. See also "Lokomotive 2 van Stichting Stoomtrein Goes Borsele" on De Nederlandse Museummaterieel Database at [], last accessed 31 October 2025. Works numbers were 737, 745 in 1924.
Both the 1940 Krupp book and Jens Merte's Krupp production list report the original 1924 production numbers. They apparently referred to their original duty serving their maker's Krupp AG steel empire in Essen.
In the 1930s, however, both underwent substantial upgrades with 745's makeover occuring in 1931 and Laura 6. This was the locomotive that operated on the L&V in Eygelshoven in 1931. The 737 may be a duplicate after its 1932 overhaul, but the Limburgische Tramweg in Roermond ran it first before it too landed on the L&V. The two remained on the L&V roster until 1972-1973.
After its retirement, the Stoomtrain Goes-Borsele (SGB) museum railway operated the Laura 6 from 1973 until it needed a major restoration. Beginning in 1999, the Laura underwent a full rebuild and emerged as #2 Borssele to continue heading up tourist trains.
