One of the best looking FBMs that I have seen and in a pretty location. Third day in a row I have found an FBM with a height tag.

Easily located FBM makes a change from road side ones - located under a Horse Chesnut tree (well it has Conkors on it) so I would suggest it not to be a Sycamore :) - FBM in Good condition.

Spotted this during the 'Castor Canter' Geocaching series (http://coord.info/GC2WC6P). A nice little find! Still in good condition.

Unusual location for FBM - half a mile from the nearest road. In excellent condition, complete with height tag 113.40ft, original "Ordnance Survey B M" plate and 1999 GPS plaque. In a pleasant location in the shade of a horse chestnut tree (but GPS reception therefore not excellent).
