G'day Sam Ball
They are Sankey Trailers
which is the UK MOD 1/2 ton 2 wheel, I know of several that were brought into Queensland a cople of years ago, and there are still 4 for sale
they have over-ride brakes, as well as handbrake, rear stablising legs, full MOD lights, front and rear,screw in MOD type (same as on 101's), as well as reflectors,they have shock absorbers, and axle articulation straps, I believe that the price is now $2500 ea, as I know that they cost just a few dollars short of $3K ea to bring in to the country in 2006, it is the duty that is the killer, as they value on current "Off-Road Trailer" new prices, as they are new to the country even though they are S/Hand
If you are interested, I can give you a Qld Ph No, as I know the owner and the trailers are in good condition,and he could probably send you a pic.
cheers
