Black Watch sgian from Ebay

[OC Richard]

You're quite right! I just looked through a couple books, and the officer's sgian of the BW has St Andrew holding his Cross.

The PM and DM wear, on their feather bonnets, different cap badges than the rest of the regiment, a sphinx just like the one on this sgian. I guess that, and the brass colour, is what made me think BW.

(I discovered that this is a Cameron Highlanders sgian.)

Just checked the Black Watch UK online shop and they sell the Sphinx emblem, almost the same as the OP'S, for officers to wear on sgian dubhs and dirks

I did a bit of Googling and the sgian I have is from the Cameron Highlanders, not the Black Watch.

A sgian just like it was auctioned as part of a group of Cameron Highlanders memorabilia.

Humm, 1940. The Cameron Highlanders were the last unit in the British Army to wear the kilt in action during that year, in France. There is a kilt with battle damage from that action on show at the Cameron Museum at Achnacarry.

That is a gem. Above and beyond it being a fine looking sgian it has a history that sends chills down my spine. 1940, deep into WWII. All I thought when I read your post was the song Green Fields of France (the link is the Dropkick Murphys version). I know it is WWI but the sentiment does not change,

The Canadian Camerons are in Ottawa, and have a museum. Unfortunately their website doesn't have a photo of their sgean dhu.
The British version of the Cameron Highlanders has been amalgamated a few times, but there may still be someone who will answer your questions about the sgean dhu. It should still be possible to find out something about the mysterious M.G. and Daphne.

Let us know.
