Windsor Diamond? Green Ashtray/Coaster,3X,Minty

Windsor Diamond?? Pale green ashtrays or coasters. No ribs in bottom for glass to sit on, no separate cigarette rests in edge, but really doesnot need them, so I can’t say for sure coaster or ashtray. Also cannot positively identify them as Windsor Diamond, but they sure look to be. They each measure right on 4” diameter, and all are in excellent condition. I have 3 and will be happy to discount a bit if you want them all. This item will also be on display at Best’s Antique Mall, Lincoln Mo. So please check with me regarding availability if interested
