Dartmoor Hedgehogs Pioneering Series

Found one of these boxes in the Leather Tor area and I was wondering if anyone knows if they are still active letterboxers or if anyone is looking after these boxes?
Assuming is a old box as visitor book was 2nd one and first stamp dated was 2000.
Both phone numbers in visitors book are no longer active and contact name was Geoff.
I have further details if anyone is looking after these boxes - excellent stamp and worth the hunt

Pioneering Series of WOM stamps was put out in the year 2000, the letterbox walking name was Dartmoor Hedgehogs, sorry I have no contact info.

thanks for the info woodford wanderers as they are nicly cut stamps - i know most of them may have gone by now but you dont know the location of any more that you could possibly pm me?? as assume owners no longer letterbox
