Holy cow! That’s amazing. Ironically enough I also found what I think is an NR and Co. rubber button as well. After these posts I took a relook at some of the buttons from this lot. I really think I have some with quite a bit of age. I cannot thank you enough. I think I’m a good researcher but I’m paling in comparison to you! I saved that tatting page in my favorites. Ridiculously helpful. And to think, I had that bag in my hand and was ready to put it down because it was 10 dollars. Never leave anything behind!!!! You think I would know this after years of scavenging...
