See Locobase 10996 for a short description of this small tank-engine design sold to several industrial, mining, and agricultural companies.
It appears that the first three locomotives were built for the Swedish locomotive firm Thunes Mekaniske Vaerstad for export to Russia's largest locomotive works at Putilov. The rest of the engines went directly to the works. To accommodate the 20 cu ft of soft-coal fuel, the bunkers extended forward from the cab over the rear driving axle on either side of the boiler.
Baldwin calculated used a 0.60 coefficient in calculating tractive effort as 5,870 lb (2,663 kg/26.11 kN)
Data from DeGolyer, Vol 57, pp. 390+. Works numbers were 42917-42920 in February 1916; 43578-43585, 43647 in June; 43660-43662 in July.
Another in a series of well-tank designs supplied by Eddystone to various foreign customers during this period. At the time of the order, this railway and artillery works was the largest in Tsar Nicholas's Russia, employing 20,000 workers.
