Alan, thanks for looking. I had wondered if it was a Countryman but decided no. Cutting width is 18″ wheels are 13″. No sign of any vacant fixing holes or brackets suggesting there aren’t any missing guards. The stainless steel guard at base of drive to cutting head could well be home made. Under the cutting disc is a thin brass cover, looks a bit like a saucepan lid, which is very well worn as it would rub along the ground. At some time the machine has been repainted with what looks like army green. Areas of original paint are a light metallic green. The machine was collected along with a Rotogardener rotatavtor.
