I think this has to better than any environmental business award. I have swallows nesting 5 feet away from my lathe. They nest in my workshop most years and are using the same nest they used last year. So far she has laid 3 eggs but has not started sitting yet. last year it was a joy to be turning away whilst the adults swooped in to feed the young.
They are copies of canisters found on the Mary Rose in the Barber Surgeons chest. Some even had the original contents intact when found with the finger marks of the Tudor surgeon still visible. These copies are for a museum display.
