They were presumably made in West Germany, most likely some time in the 70s. The material is solid wood. The brand is NOT "Pöhler und Schilling" or "P+S" despite looking very similar. There are no other logos, text or stickers on these things.
Any help is greatly appreciated!
No worries, I'm happy about any lead! I looked into spendor and it seems they always had logos with the brand name written out. I appreciate the suggestion though!
