Hey all, I believe I have an old ball end open comb 3 piece from the 20's. Did research with the info provided here and have nailed it down to that time frame I believe. It has been in my family for quite a while but never cared enough to pull it out and take a good look at it, you all inspired me so ha, here we are. She has a beautiful patina, but dang it looks aggressive! Anyone use these and can comment on them. I love the feel, weight and length of it, thinking I may give it a whirl myself and let my Slim get jealous.
