@gardencat I think they're "horse brasses" that would normally be tacked to the yoke around shire horses when they delivered barrels of beer on carts. This door will remember those days!
@onewing The first time we visited family in Australia when I was 10, we had a half day trip to be taken to the oldest house in the area. 150 years old- we at the time lived in a rather run of the mill British 200 year old home!
The stone step looks fantastic too. Nothing as old as this in Australia. I miss old things sometimes!!
