Aye, 'tis indeed.

And so is the Whistler label you posted, casper. Couldn't see it first time round.
Its got me wondering if that Walter Locke paper label I posted earlier with the apparent pocket is simply missing an embossed maker's name, inserted from behind.

Here's another uncommon label for a gun in my custody, the shortened and re-regulated "double slugger" made from a William Griffiths boxlock that was lopped by 5 inches following damage to the muzzles.

Apologies for the poor quality, had to crop it from a web-image of a cased gun.
