Ordnance QF 37 mm Mk I ammo box

[Charlie Down]

Hi, I'm researching the Bofors 37mm M1936 anti tank gun that was in limited use by the British from 1939 to early 1942, under the designation Ordnance QF 37 mm Mk I. It appears that the wooden ammo box commonly used held 30 x 37mm rounds in 3 layer of 10 rounds in cardboard tubes. I am currently researching details for a LRDG Ford F30 Bofors gun truck used until early 1942 and seeking details of the ammo box seen in the photos attached. All the information I have found relates to Swedish or Finnish export ammo boxes, of wood or metal construction. Any information would be greatly appreciated. Many thanks.
