If any aditnow guys are ever in the North Devon area you are welcome to give us a visit, our mine is very old some parts date back to the 13th century and other bits are victorian. No ropes required, nearly all opened up bits are easily accessible except 2 places require a ladder to get into (not counting all the ladders in the shaft). you can find all my contact details on our web-site, combemartinminers.co.uk 😉
