Vintage mid century Gold Tone Septor Pin Brooch

Vintage mid century gold tone septco pin brooch...I believe it's from the WW1 cause it was found with a couple more things of my grandfather that was in the war had... like an old 1920 lighter I posted and some other pins that were worn on his uniform but don't quote me on it... it's very nice piece which I think everything is still in tac- nothing missing it doesn't look like i faultless for everyday use. first-class materials and excellent craftsmanship ensure long-lasting durability.
