If it helps any, the earliest dated rune is from a bone comb, and have also been found on wood and wax. https://en.wikipedia.org/wiki/Bryggen_inscriptions https://en.wikipedia.org/wiki/Bryggen_inscriptions says that find helped show that runes were used for things besides "inscriptions of names and solemn phrases." This would suggest that were runes widely used in central Europe, on wood, then it would still be possible to find traces of that use. FWIW, knowing basically nothing on the topic, I did a Google Scholar search with 'rune "central Europe"', which returned things like: "Runes from Lány (Czech Republic) - The oldest inscription among Slavs. A new standard for multidisciplinary analysis of runic bones" - https://www.sciencedirect.com/science/article/pii/S0305440321000030 https://www.sciencedirect.com/science/article/pii/S030544032... I also found that Old Hungarian script was a runic script - https://en.wikipedia.org/wiki/Old_Hungarian_script https://en.wikipedia.org/wiki/Old_Hungarian_script , usually carved on wood or sticks.
