The jockey wheel is very very stiff to wind up or down even if there is no weight on the trailer. I assume it needs some grease, but there's no nipple and no obvious way of lubricating or getting at the winding mechanisim. Any advice appreciated.

That looks familiar - no telling if the same though.
Support the trailer on a block and draw the jockey outer up as far as possible so the wheel is well off the ground - then unwind the inner until the wheel section falls off. The outer piece? will have a threaded bar that requires cleaning (wire brush) and lubing (lots of grease). A bit of grease in the nut in the other unit and then screw it back together.
