Description
This is part of a series of nine drawings made for the non-fiction book "The Fortified Region Focsani-Namoloasa-Galati" published by the Romanian Military Museum about the eponymous Fortified Line (also known in English as the "Sereth Line" and by it's abbreviation "FNG") built by Romania for defence against a presumptive Russian invasion during 1888-90.

Fifth drawing, showing the 5.3cm Schumann-Gruson Fahrpanzer in transport configuration, mounted on its horse drawn carriage.

This is the first type of the 5.3cm mobile turret, designated Md.1888 in Romanian usage and I've decided to draw it because there are no extant examples and only a few pictures, since this turret was almost instantly replaced by an updated type, referred in some sources as Md.1890.

EDIT- it appears a Md.1888 turret survived and is currently being restored in Bulgaria - this can only be a Romanian turret captured at Tutrakan/Turtucaia, since although the Bulgarians also purchased the Fahrpanzer, they did so only in 1892 so all the turrets they had were of the third type, not the second.

The transport carriage is pretty straightforward - a platform made out of steel girders with two wooden wheels 1.4m in diameter. The axles are set up at a 5° downward angle and the whole weight of the contraption was 800kg.
The turret itself weighed an additional 2,000kg and the whole thing was drawn by a single horse or ox harnessed between two 3,4m shafts, with the option to add two more on both sides in difficult terrain.

On this version of the cupola/carriage combo, the driver sat on the extension at the back of the turret, and, when that was deleted on the M.1890 version, the carriage was modified by adding an articulated front end with two extra wheels and a separate seat for the driver .

The other drawing in this series can be found here:

Cover, showing cutaway through 5.3cm mobile gun turret
Plate I, the 3.7cm mobile gun turret and transport carriage.
Plate II, the 3.7cm gun and ammunition.

Plate III, the 5.3cm mobile gun turret in its concrete emplacement .
Plate IV, the 5.3cm mobile gun turret in transport configuration.

Plate V, the 5.3cm disappearing cupola.

Plate VI, the 5.3cm gun and ammunition.

Plate VII, the 12cm gun and mortar armoured battery.

Plate VIII, the 12cm gun and mortar and their ammunition.
