New to the collection... Picked this one up at the Toronto Military Show this last weekend.

WW2 US 20mm Hispano M21A1.
A nice, complete, cutaway fuze... Mk 26-1 air column detonated.
Steel case with star crimp (economy mass production techniques).
Fuze and projectile maker marked "Y.A.".
...unknown?

Just thought I'd show a little of my collection.
Hope you enjoy.

Cheers,
Brad
