Re: the dinky mail slot..We have the American Metal Arts original. Just last week we removed it for the first time ever as our house exterior is being painted ( yes, in the rain..) and true to WNP discovered this fact and were able to connect to Ohmega Salvage in Berkeley who has “thousands of numbers” from our homes. Lucky for us, they had an extra number “2” which was in need of repair. The zero (0) and number 6 are still good as new. This was so much fun!!
