Thank you for your email
I have had confirmation that this is an orienteering punch.
However this 'addition' is nothing to do with Ordnance Survey and it is
likely we would have to remove it should we (or any other surveyor) wish
to set equipment on the Trig Pillar.
Thank you for informing us however there is no further information we
can give.
Kind regards

I wouldn't want to carry many of those things around in my rucksack if I was an orienteering marshall.

GEOCACHING
This pursuit is becoming addictive. You may notice the logo on my blog which automatically records the number of caches I have visited after I have recorded them on the Geocache site. So far I have found sixteen, one of which required two visits due to my ignorance of the affairs of the band called Oasis and something to do with "Wunderwall", knowledge of which was required to interpret the clue about the location. The solution was gleaned from my daughter Jill who was appalled and amused at this gap in my education, and I was forced to listen to the song! Looking at profiles of other geocachers I see some who have found several thousand caches!
Here are some Geocache pics:

PROPER WALKING
In the last couple of days I printed off sheets from Memory Map with the route marked for my proposed walk from Lowestoft to St Bees Head which I intend to do after walking in France during May and June. The print off runs to fifty three pages of A4, and this gives some enlargement of the 1:50000 map. I will probably post half of these ahead to save weight, although they are not too heavy, and certainly much better than carrying all the maps.
