Very interesting documented facts found on the history of the red paint. We use linseed oil for doors and window frames here to preserve them from wet/dry rot.
Linoleum I also learned something new always thought there was some form of plastic in the manufacture, we live and learn something new every day.
Thanks for most interesting read @thekittygirl and your ongoing series of barns in your region, so picturesque on their dwellings.
How interesting, that you do the same in South Africa! Thanks for letting us know! 😀
