Hi, Daimler Armoured Car MkI has the holder with a round base plate with three bolts to attach to the gun mounting.



The MkII has a rectangular base plate as pictured in the Chilwell Catalogue No. 60/117 in Fig. 216 and not square as Andrews example is.

Apart from the base plate it looks very similar.

Hope this helps?

Cheers,
