Vintage Ice Tongs

Recent yard sale find. I did not know what they were at first but soon realized that they were old ice tongs. I never used any growing up, we always stuck our hand in the bucket or tray and scooped them out ! lol I was just wondering what time period they are from and if any one else has any, or seen any like these. They were made by a company in Germany called Luna and they are stainless steel. I tried them out the other day and they worked great !! They are too time consuming for a country boy like me, cause I can usually pick up 4-5 using the "hand" method. lol Thanks for looking, Thrifty Gypsy
