That's a brillant find. Extremely interesting reading. I have been on the Ben often and find it a bit sad to see the old observatory in such disrepair and often wondered what it would have been like. That was a great insight even though only one persons view or memory. I sometimes wish it could be restored to its former glory but it's not really an option. What a hotel that would be today, though I'm sure others would disagree.
Great stuff - cheers.
