Vintage Owens Illinois Glass Bottle. Probably catsup. For Sale

This vintage Owens Illinois Glass bottle is likely a catsup bottle, made clear in the United States. I cannot find this exact shape or size anywhere for comparison and positive ID. The bottom has numbers 1220, 20, and 12 [ Owens symbol ] 1. The sides are fluted from neck to mid bottle. The base has shallow fluting all around. The glass is thick and heavy. Found in central Texas.
