Help with Mills No. 5 Markings

[RCA56]

Greetings all,

I have a Mills No.5 MkI with some markings I have not been able to identify.

The body has a Foundry Mark with the letter "U" and the centre tube is marked "J.B.B. Ltd."

Can anyone here decipher these for me?

Thanks very much for any help you can provide.

JBB most likely JB Bruce Ltd, Havelock Works, Birmingham - a war and pre-war brass foundry. During the war made: "Magneto parts and aero fittings, fuze parts, hand grenades and centres and plugs. Terminals for laying out cables. Air pressure pumps. Detonator plugs."

That is a nice grenade, any chance of a picture of the base plug, this is my example, its been ground on one side a 2 threaded holes might have been on a display board at some time but did not have any other parts with it just a bare body,,,,,,,,, Dave
