I noticed a curious singer collectable on eBay. I'm not interested in buying it, and I'm not the seller, but I figured someone on here who was interested in vintage club stuff or vintage racing stuff might be able to shed some light on the cryptic name or might be interested in it. It's a vintage dash plaque that simply says "Singer Owners Club Cha-Shi-Lom October 24, 1959". What was "Cha-Shi-Lom"? It must be short for something.
