Light Tank VI map board mount?

[Jack Geratic]

Trying to determine what exactly is the contraption attached to the copula in the following photographs. I thought it might be for AA, but a map board mount has been suggested. Any more info would be greatly appreciated.







regards,
Jack

Humber Armoured Cars had two spikes on the roof to mount a similar map board so I would suggest the same.

How about a windscreen??

Neil, I think you got it right - thanks!

A Humber photo search gives a similar structure:







Now you say the board was fitted over a pair of stakes- I gather the latter are welded in place? So the board is removable, and has no variable position option when in place?

Correct and that looks like my old Humber.

One caution from memory it does not feature in any Humber Parts List and I made the frame on mine. It could double as a windscreen with a sheet of perspex bolted on but did the army care that much about creature comforts at the time.

Neil, so you are saying this particular piece of equipment was a field modification, not a factory made part?

Was it attributed in any particular vehicle, such as a commander or artillery observer assignment perhaps?

Thanks again,

Jack
