Ruger Yankee Model's #300 & #301
Post by T.A. Workman » Mon Dec 13, 2021 12:07 pm

Gentlemen,
I've finally paired up my Model #300 Yankee Spiral Ratchet manual return screwdriver with a Model #301 (top) automatic return variation.
These were produced by THE RUGER CORP in 1947 and were Bill Ruger's pride & joy. He designed and built the machine that cut the spiral shafts, six at a time.

Note the difference in distance of the Company Roll Mark, manual (r) 1/2" & auto (l) 5/16".

Color me jealous! I'm still searching for my first spiral screwdriver,, and you have both varieties! VERY nice!

That is really great. Ruger made good tools and the fact that Bill Ruger designed one of the machines to cut the threads is a neat fact.

Congrats Terry.....I have a pair too

Thanks Radical,
But my set is missing a Breast Plate Drill to hang out with this holiday !

Terry if I can do it I am certain you can too.....
The one I bought was the only one I have ever seen for sale.....
So you don't have to worry about me chasing the next one

There is a third variation..
