We had a radiogram with a triangular fibre stylus, when it started to wear after a few records dad would sharpen it with a small tool. I also recall one which played both 78s and LPs, the stylus cartridge could be turned over, having a 78 stylus one side and an LP one on the other.
I still have one of my parent's 78RPM 12", Glasgow Orpheus choir singing "All on an April Evening".
