Compressor

One of our local stone masons has a lot of old stuff lying around in his backyard. This old compressor is one of his. Disposing of waste is expensive, so I see the point of keeping it. And maybe the price of iron will rise in the future.
Actually, it is not in his backyard. Probably due to the mere amount he had to expand to his neighbour's property.
