Internal layout of 'Tin Van'

[Mol_PMB]

What was the internal layout of a Bulleid 'Tin Van' - the luggage variant numbered in the 2700 series?

Was the guard's office partitioned off from the luggage space? My impression from photos is that the interior was entirely open-plan.

Since they acted as a guard's van, I imagine that there must have been at the very least the following, but I don't know how they were arranged:

• a seat
• a desk
• a handbrake

Some photos give an impression of a fire extinguisher and a shelf at one end:

Has anyone on the forum got a drawing, photo or recollection of how the interior was laid out?

 

I have found this information for the heating variant - both a drawing in the HMRS collection and a very nice model by David Malone illustrated in N.I.L.

The luggage van variant could have been similar, but without the boiler compartment and tank.
