mouse: Finally made it up to this one today to retrieve the coin and assess the cache.
I have decided it's time to archive as the puzzle element is now missing and I don't have parts to replace it. Instead I had hidden another traditional a short distance away as part of Birdie's Peach <a href="http://www.kammneves.co.uk/bpjc2/">Birdie's Peach Jar Challenge 2</a>
Thanks to all that visited and also for the owners of the coin which has been stuck here far to long. I really appreciate your patience.
