Thanks everyone for the great responses and ideas to how I can figure this out.
-No I didn't see a GC code anywhere in or on it, it was quite small and only had a log inside.
-No I don't remember any names, but I can go back and check it out and double check for a GC code too!!
-It was definitely wasn't a letterbox.
-When I first started caching I remember reading that there was one there and I went to look but didn't find it (no skill at that time).
-I'm reasonably sure there was a recent date in there before mine.
- Been under the weather last couple of days,will go back in the next day or two and check it out and get coordinates as well!!
Thanks,
