Royal Navy vehicles

[Larry Hayward]

Guys,

Here is another RN vehicles in the background of this shot of a Fairey Barracuda.

I'm not hot on coach identification so perhaps someone will know. No doubt an impressed one.

What I thought at first was a shaddow turns out to be a two tone grey camo?

Any thoughts on whether the coach has an added superstructure or is that on a building behind?
