In my never ending search for knowledge I have been looking into grafting two unknown cider apples I discovered onto a good root stock, I have quite a collection of old gardening books so began trawling through them to see what I could find, the image was taken from “Practical Gardening and Food Production in Pictures” by “Richard Sudell” I believe it was published around 1946.
Another two images that may be of interest are from “The ABC of Fruit Growing” by “W. E. Shewell-Cooper” 1954.
