Very Tall Country English Armchair, Tennis Umpire?

If this were a normal height it would be a typical Lancashire ash ladder back rush seat chair. We have seen many of those, but never another like this. The seat is three feet off the floor. You will need a step stool to get in it. Our best guess is that this may have been for a tennis net umpire.
