The Victorians were very ingenious people and were always looking for ways to 'make do' if they couldn't afford something more expensive. Local tin smithers developed Tin in a variety of shapes and styles including brick, slate roofs and as we see here stone. As they say, timing is everything, and in this case the original tin must have been in good shape when it was covered because it actually is in good condition. Holes are being filled and it is being repainted with a good rust inhibiting primer and may eventually be 'faux painted so it more closely approximates the stone foundation.
