Data from DeGolyer, Volume 60, pp. 58+. Works number was 53885 in October 1920.
See Locobase 4953 for the full description of this French light military railway design. Quoting from that record, we note that illustrations show "shapely stacks on each end, tapering outward from the base to contain the spark-arresters topped by a tall cylinder with lids on the top. Slab side tanks flanked both boilers; one held a convenient hose. The cab had a keyhole opening and a cupola at the top. It's hard to tell if the fireboxes are accessible from each side, but it doesn't seem so. "
This seems to have been the only Japanese example.
