I think it was just a matter of patience and space, this was part of a particular group of restored mower in his collection, he sold 2 villagers, and then sold me the rotoscythe and the lawn cub, the remaining members of the lot were simply thrown into a scrap skip when they did not sell.
The coil is fairly simple, and I may be able to look into having it re-coiled, it is also similar to some other coils, and may be able to be adapted from one.
From what i can find out, the condenser is nothing specific, and should be replaceable with one of a number of different condensers, at least till a more suitable replacement part is found.
