Hi JT
I've just posted the pics of the "homers" as we used to call them when I worked in a plastic injection moulding place.
Sorry that I didn't see your earlier post requesting a pic of the WM version but I'll dig this out for you.
Chances are that it COULD be a very heavily plated one but I did do a WEE test and examined it with a jeweller's loupe and couldn't see any brass. Soon brush off with wear....
I got the name wrong on the stamped one, as it is
"A. SHACKLETON" and it has been done very well.
I do have a 1916 badge with the lady's "factory work card" and this could be the Anderson one.
Yet ANOTHER one has little "home made"(?) year bars "1916-1917; 1917-1918" soldered below the lower arm of the triangle with small holes for the placing of rings like some associations still do.
