Set of Jaws for 3-Jaw Machinist Metal Lathe Chuck Manufacturer Unknown

Description

For sale are a set of jaws for a 3-Jaw machinist's metal lathe chuck. Each jaw is marked "711 0542" followed by numbers 1, 2, and 3 separately on each jaw, but there is nothing to indicate who the manufacturer was. I bought them with a lot of other tools and there was no chuck. So I don't know what they fit. Tried to provide as many measurements as I could in the attached photos, but please let me know if you need any more info.
