..... Appears to be the rohrwagen. 15cm sFH M14 of the Ausro Hungarian Army. When traveling, the piece was moved in two loads. The only surviving example of this tube-wagon I had known resides in the Musee Royale in Brussels. Does this example still exist at the Victoria memorial and is the carraige also displayed ?
I'm a Leading Seaman in the Victorian Naval Forces, so I'll ask my local "shipmates" if they know anything of the fate of this piece (we're dedicated to attempting to preserve what is left of HMVS Cerberus, but many have interests which overlap with this kind of exhibit)
