sniper answered your question correctly. These are not rare or super valuable. I have one for my .50 and one for my 1919. It was much harder to find one for my .50 but after I found one, I found 20.....that's the way it always goes.
There are a few variations in T&E's and I hope that Dolf Goldsmith goes into that stuff in his 3rd Browning book
