Have you been able to decipher the meaning of any of it? The -2 or -3 for example? And, what's the deal with the 9/16 one? Does the socket come off of it?

I have not made anything of the meaning.  The 9/16" is a fixed socket.

Great collection O.R.

Thanks!  Many of the tools have come from members of this forum.  Believe it or not, I have a record of where each came from - so that when they're placed on the board the contributor may be noted.

Wow, your collection is coming along very nicely. I was just thinking about all the Indestro variations in another thread. It may be a toss up as to whether Thorsen has more. They were pretty sure about that 77 though. Almost everything needs a 77 in it :) !!

Thanks, Kit!  As you know many of these fine tools came via you.  Yes, you now have me thinking on those Indestro ratchets.  I will venture a guess there is more to the "77" than just it's common use.  Why is this company so dang hard to research?

Great collection, thanks for sharing!

Have a JCPenney 1/2" drive set, I think it is Thorsen sourced.

Will dig it out, would be fun to verify.
