Marston Sunbeam outer timing cover with smaller external oil pump housing Flat Tank?
Cast number inside the timing cover is 941M.
The oil pump has damage in the usual place. I have shown the damage to the oil line connection in the images. Without removing the pump housing, I’d suggest that it’s just the housing as there is no impeller visible.
Distance between the fixing holes (centres) is 3.5″ or 88mm
