Few wrenches yesterday

[MarlynOC]

Found a few old wrenches yesterday
1 J H Williams & co Brooklyn NY with a W on it 3/8 and 5/16 printed on it but the sizes are closer to 3/4 and 5/8"
2 Same type of Co name? at one end stamped 726 other side 5/16 and 7/16
sizes are 1/2 and 5/8"
Any ideas about them?

Sounds Like Whitworth sizes.

What I was thinking they were. But Made in USA was what threw me off.
