Inert WWII Scotish manufactured No36M MKI Mills Grenade

This is a rare early WWII Scotish manufactured No36M MKI Mills Grenade. The body was made by Carron Company of Falkirk (makers initials CC) , and the base plug by R & A Main also based in Falkirk, Scotland (makers initials MF) dated 1940. The drilled holes were added as an obvious form of deactivation and may indicate that it was used by the War Department / MOD for training.
