Here are my two, as mentioned above. I took a speculative punt with a chap known to me at a Frenchicon arms fair on the Somme fifteen or so years ago, but went into it knowing all the possibilities. It would be nice if the consensus said they were genuine, but I shan't cry into my beer if they are not.

Bitterly disappointed M&S means Myers & Son. I have been looking out for one in the hope that they were made by Marks & Spencers.......
