Hi, just wondering if anyone can ID this solid 37mm projectile for me ? It is 36.4mm diameter at the base, 78.3mm long, and weighs 480g. Thanks very much.

It seems to be a French solid shot Boulet de Rupture Mle 1916. Our French members will confirm .
Mine is similar but 79.5mm long and weighs 495 grams with driving bands. Similar numbers between bands.
