Cache is a 1.3 litre box with plenty of room for swaps, hidden at N51 aa.bbb W003 cc.ddd where:
aa=(P*K)-L
bbb=(Q*G*M*F)+R+(S*T)-V
cc=(U*J)-V
ddd=(D*Y)+W+X+C
Notes:
16/11/15: Physical cache location changed. The solution was altered to suit the new physical cache location.
3/4/18: The formulae were re-worded for extra clarity and re-ordered to make it easier to follow but the solution remain the same.
27/12/19: Updated some of the virtual locations, as some sites had closed down
08/01/22: Box seal had perished, box and logbook replaced and cache swag refreshed. The Mollyjak camo bag lives on!
