I have acquired a 'Nautical Almanac 2011' through a customer who no longer needed it.
It isn't the standard navigation Almanac - I think its for Astro Nav as its a collection of times and angles which doesn't make much sense to me.
If its of any use to you collection from Portsmouth, Fareham or Southampton (Itchen) can be organised.
Just googled it:
Marine Society Bookshop - Admiralty Nautical Almanac 2011
Any contribution to the beer fund is more than Welcome
