Vintage Bicycle Rear Luggage Carrier Rack, Barn Find, Schwinn 9 Hole Style

Here's a vintage bicycle luggage/package carrier rack in original, as-found condition. We found this while scouting for antiques in an old barn and its just as it was discovered. It measures about 20 1/2 inches long and is 4 7/8 inches at its widest point. The mounting brackets are about 14 1/4 inches long. This rack has a 9-hole pattern that looks like a Schwinn product but there are no markings that we can see and aren't completely certain. It has surface rust but its a restorable piece and has a great patina just as it is. There are remains of a reflector on the back. Straight and structurally sound, this carrier is a nice find!
