My grandfather was a salesmen from US Steel and this was found with his belongings. I am not sure of the year of manufacture, but I would guess it's from the 1950s-1960's.
This is a Zippo (Brandford, PA) steel money clip with nail file and pocket knife branded with advertising for US Steel, specifically Steel Processing and Supply Co in Springfield, MO.
See photos for excellent condition. I don't think this was ever used.
Sold as-is. No returns or refunds. Smoke-free. Shipped via USPS.
