andytalliss: Thanks to all of the people who attempted and found this cache. The road to the Ancholme is not to clever!.
Although I archived the feeder caches some weeks ago I did not have the time to retrieve the main cache until yesterday.
Amazed to find that the drum was still in perfect order in the same p[lace that I left it. I will now be able to reuse the contained somewher else.
