North Bros. Mfg. Co. "Yankee" No. 30 & N0. 130 series
Spiral Ratchet Screw Drivers

Top to bottom:
No. 135A (quick-return light pattern)
No. 130A (quick-return standard pattern)
No. 131A (quick-return heavy pattern)

Non quick-return models are No. 35A, No. 30A and No. 31A respectively.

These screwdrivers, especially the quick-return heavy pattern (No. 131 & No.131A), were much used in the truck cab and body building trade to which I belonged in the late 1940s. Just about every craftsman and apprentice had one in their tool box.

The images on this page mostly relate to the "New Improved" models (suffix A, post-1924) for they are the ones most encountered these days. There is actually very little functional difference between the old and new models.


One obvious visible difference between the pre-1924 models and the post-1924 "New Improved" (A) models is in the form of the handle/barrel ferrule:

PACKAGING

Caption describes image

"YANKEE" spiral ratchet screwdrivers were packaged and sold in the familiar cardboard packing boxes to which was affixed a yellow paper label that described how to use the screwdriver and outlined it's features.

Packing box top labels were changed to reflect the "A" suffix series tool designations (mid 1920s to late 1930s) and instructions were updated if needed.
