Victorian postbox

Seen on the wall of the visitor centre by Queen's View at Loch Tummel. Sadly the view itself wasn't at its best while we were there. Must go back later in the year, it's a beautiful area that I haven't been to for ages. I had always thought the name of the viewpoint was from a visit by Queen Victoria but signs at the centre say that it could be earlier and named after Queen Isabella, wife of Robert the Bruce of Bannockburn fame.
