Over the years I have had a lot of the top wrench in the first two pictures. Made in the USA, Drop Forged and no sizes. The second wrench in the first two pictures is identical except for the size and matches another wrench in my collection. However, in the second picture note the F-123 on one end. Lastly, the bottom wrench with "Smiths" on one end. I had never seen this type wrench with a name on it and I have had a lot of them. Any comments.
