We had one of those. Wish I could remember the make. We also used the
spray gun attachment.

This was the one we had

The hose and fitting look very similar, as does the red (metal?) casing,
although ours was blue. The white ends are a little different, the inlet
end being black and a little more rounded. The outlet end also being
black. I can't see the outlet end, but ours had a cast metal section,
with knurled screw in the centre. Ours also did not have the handle on
top, instead having a luggage type one - a horizontal strap, with the
ends in metal covers - along the top of the casing. Underneath are a
pair of metal skids.
