This internet search was provoked by Rob. I have found a few photos of the two guns at Eilean Donan Castle, but this one (in Sicco2007's flickr pages) is the best I've seen so far:
Unlike Canada and Australia, surviving WW1 trophy guns are rare in the UK. Does anybody have any better photos of these two, or more information on these two, or indeed any photos of any other surviving trophy guns in the UK?
Wow! Very impressive. I'm not aware of any other trophy guns surviving in the UK - my village is supposed to have one buried and I know someone who saw it being buried, but despite an appeal in the local papers I heard nothing more
Found another trophy gun in Scotland - at the Clan Cameron Museum in Achnacarry
From the museum's website, "This artillery piece was captured by the Queen's Own Cameron Highlanders at the Battle of Loos, during World War I. The regiment suffered significant casualties, with Colonel Sir Donald Walter Cameron of Lochiel, XXV Chief of Clan Cameron being wounded in the action."
Another 7.7cm FK 96 n.A. I don't know anything about the geography of Scotland but I get the impression the surviving guns are in fairly remote
places. Perhaps the survival of the guns is due to an effect which can be seen in the WW1 guns in Australia. Places where guns were allocated and
were on railway lines are unlikely to have surviving guns. The theory is that the local councils couldn't sell the guns for scrap if it was expensive to
remove the guns - until about the 1960s in Australia road transport was not cost competitive with rail.
