brockhouse trailer

[wolf]

Hi,
I'm new on this forum.
I just bought this trailer:

the seller told me that it is a sankey radio repair trailer but i found a ident. plate who marked "Trailer 1/2 Ton Cargo Brockhouse FV2301 A"

So there are a lot of sankey parts on it, and the way the unit is fixed on the chassis is the sankey-way/
It has Landrover wheels. but the wheel arches are totally different.
Any idea where I can find some specifications of this trailer?
thanks a lot.
Willy
