Regimental Leg Tattoos?

[BoldHighlander]

I thought about placing this one in How to Accessorize your Kilt (or maybe The Heraldry Forum ) but just decided to place it here instead.

Anyhow, over in the thread Canada's Highland Regiments I first mentioned this, but wanted to expand the question & thus thought it'd be better served in it's own thread.

I recently ran across an interesting photo & thought I'd share it and the story behind it with the rabble.

Kiltmaker Robert MacDonald of Vancouver, BC; is a former Seaforth (Highlanders of Canada) and on the belts & blades section of his website is the following photo & caption which I wish to share here:



In most regiments, the use of the sgean dubh is restricted to pipers, serjeants and officers. This has been circumvented by the ever-resourceful 'jocks' with the introduction of the 'Regimental tattoo'.

In the Seaforth's, this takes the form of the Regimental badge tattooed on the right calf and placed so that the top portion is visible above the stocking. The Coronet and Cypher look somewhat like a sgean dubh with the advantage that airport security doesn't pitch a blue fit about it!


Interesting.

My question:
is this practiced by any other kilted regiments (not just in Canada but anywhere in the world), and if so does anyone have any photos of these leg/calf tattoos they would be willing to share?
