Came across this listing recently https://www.ebay.com/itm/Gretsch-Cadillac-Tailpiece-Gold/313381536122 The descriptions says only Gretsch Cadillac Tailpiece Gold. Condition is "Used". Not sure what year but it looks pretty vintage classic very hard to find functions great looks awesome. But it looks like a newer one to me that someone did a horrible relic job on and turned it pink. What kind of metal is under that plating anyway?
