Thank you for the M 19 Bill!

This is the British version of the airborne Bofors gun. The Canadian version you can see on top of page 1 of this thread.

The Canadian version was called "Bantam" carriage. Was Bantam the producer?

What were those guns and carriages called officialy? Mk ??

Answer;

ORDNANCE, Q.F. 40-MM., MARK 1/2 on
MOUNTINGS, 40-MM. A.A., MARKS 9 AND 10 and
PLATFORM, 2-WHEELED, 40-MM. A.A., MARK 1

The Ordnance was the standard Mk 1* gun fitted with a muzzle brake to preserve stability during firing because of the lighter mounting and platform.

The Mk 9 mounting is a modified Mk 3, while the Mk 10 is a modified Mk 4. The frame, platform and seats were removed and replaced by others of different design. The electrical gear and the shields were also removed.

The Mk 1 platform was a new design, having 3 girders ( or outriggers ). Two were swung together to form the towing bar, while the third slides in and out of the platform.

Brakes were Warner electric, as used on other British heavy artillery pieces.
