Who made there 1/4" ratchets?

They are nice ratchets but my all time favorite Craftsman ratchet is the Plomb made.

Then that would be the era prior to MDF?

In keeping on topic, here's a pic of the frankie rat taken apart.

Then that would be the era prior to MDF?

According to lauver in his amazing Craftsman history thread http://www.thegaragegazette.com/index.php?topic=867.0 Circle U (Plomb made) was 1944-1948. It seems the Circle V (MDF) was 1946 to to 60 something. So there may have been some overlap.

He does a great job decoding the marks and providing the history of the brand. Well worth reading.
