Early bedford radio truck

[John A. Rippingham]

Hello

Has anyone come across anything like this before? I always thought the MWR's were brought in to cover the loss of the 8cwt trucks pu's etc, but these pictures show an aeroscreen Bedford Mw fitted for radio. The pictures are from the wireless for warriors book.
Have any of you chaps into the wireless equipment seen thes pictures before anywhere else? or if there are any more similar? I visitied the imperial war museum last year and didn't see anything like this there. So guess these have come from another archive. I'm also presuming there may be other photo's showing the engine, and other views.
The tread on the spare tyre seemd odd to.
