A few weeks ago Mike Gill carried out a gradiometer survey of the north of site and we were intrigued by the large magnetic anomaly which was apparent. Our first plan was to site a new pit on where we believed the anomaly to be but this revealed no significant metallic objects although yielding similar layering and pottery finds to other areas of the garden. We then employed a metal detector to look around the site of our new pit and under the edge of the spoil heap we did indeed get a strong response from the detector. The response was found to come from a a couple of large nails and a spike-like object about 0.5m long, all in the top soil with the spike being buried vertically with its top about 0.1m below the ground surface.
As such it would seem to be unremarkable except that on closer examination it has a small wheel about 20mm in diameter mounted by a rivet in a slot towards the end of the spike which has been flattened into a leaf shape. We are puzzled as to its purpose – any suggestions? – from its situation we would estimate that it is probably of recent origin (within last 100 years).
