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!
Heya, might be 'spendor'? Think thats their old logo...
Edit: now im second guessing myself as I can't find anything to confirm my memory. Sorry if I lead you down the wrong path here.
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!
