These are ZASM “B” number 230, “Jan Wintervogel” built in 1898, originally from Waterval Boven and Class 4AR number 1555 of 1913 vintage from the Millsite compound.
Number 1555 has been reunited with its tender which has had new bearings fitted together with new axle box covers.
Once the work is completed on number 230 the team will start on number 1555 which is a much more extensive and bigger (literally) project.
