A reasonable number of these must have been made as a number of the Balkan states had them & used them. What little I have found suggests use as a mobile pillbox. In fact they seem to have more use in "peace" than war being noted as an invaluble aid to frontier & border gaurd units.
Hi Brennan, the Fahrpanzer was widely used in WW1, the curious thing is the patent details use in the field in temporary fortifications, and these were of course used in that way on the western front..... perhaps gruson foresaw the development of trench warfare.....
Gruson made a living selling fortification emplacements. The turrets of Przemysl, for example, were Gruson contract works. The Fahrpanzer was intended as a close defense system within the complex. Held under cover, 'till a ground assault was eminent, they were designed to be run out to prepared positions on light rail networks.
Hi 28juni14, sure a version of the Fahrpanzer was used as you say, Untill I read this Patent I was under the impression that this was its only intended use.... However in the patent Gruson specifically says these are intended "for use in the construction of temporary fortifications or trenches" and provides an illustration of the idea, he does mention reinforcing the position with "masonry or other means" if its "intended to be of a more permanent character".... Maybe this patent predates the idea to use them in permanent fortresses as point defence, however it is a very simple version and lacks the sofistication of the fortress Fahrpanzer, indeed Gruson makes a virtue of its simple construction... The curious thing is that in the end the fortress Fahrpanzers were used more or less as originally envisaged by this patent... ie as hardpoints in a temporary field defence....
Brussels has one. I tried their site but there's something technically not ok today. A picture can be seen at http://www.forumeerstewereldoorlog.nl/wiki/index.php/gruson 5.3cm L/24 Fahrpanzer.
This would partly fit with what I gather is the most frequent use of them as supporting border crossing / frontier post positions or paramilitary / rebellion suppression actions by the Balkan states that had them. Here the issue appears to have been mobility & ease / speed of initial implacement when compared with the costs & time of (even light) permanent constructions. The clear implication is that these units would then be "recycled" to another problem point.
I was last year in Brussels. I took these pictures below. Please take my apologies for the bad quality. I took them with the camera of my mobile phone.
IIRC there were two types. Romania bought over 300. Christy Campbell makes a somewhat ill-considered reference to them in Band of Brigands:
"The Romanians had built a strange system in the 1900s on the designs of a Prussian army engineer, the 'Sereth Line' in Moldavia which featured moving armoured cupolas on railway tracks. They were described in the contemporary literature as 'mobile forts'. A self-propelled land fighting machine was at the mad inventor stage."
