Thanks. It does have a dot pattern as nothing I have seen in my research.Proto never used that grip pattern on the top one to my knowledge
Thats it Fort Pit. You guys amaze me. I guess its (time behind the machine). Now I'm off and running again. Thanks.
Hell, that would pass for pristine in my neck of the woods.A buddy of mine saw this ole discarded box and grabbed it for me.
It needs a bit of work
I’ll send one along in the next care package. The older one has owners markings. Do you mind those?What would you want in exchange for one of those 1/4 sliding T handles?
Any way you could make a pdf of that?
I’ll take a look when I get a chance.

Most of mine do NOT have slotted screws and don’t come apart easily. It seems that there may be a correlation between slotted screws and unreinforced hanging holes. Here are the results of the survey. Only the 4” Proto LA and Mfd. without reinforced hanging holes have slotted screws.Since you had all those out, could you tell me if those have slotted screw adjustment shafts, or are some pressed in? If there are any pressed in, do they all have opposing holes that let you press them out? Just trying to figure out when the transitions occurred. Or I should just ask do you know when they went to a press fit and when they did away with the hole that allows pressing it out. Thanks.






I think that the pressed in screws were a Stanley Proto thing. The ones with the opposing hole to press it back out is Ingersoll Rand, and I am pretty sure all of the ones with screw are before proto was bought out at all. I do not know if early ingersoll rand adjustables have screws or not.

The next two have screws.
I hope that tells you what you wanted to know.

You’re welcome. I tried to capture all of the date codes. Happy to contribute to the collective knowledge. I was surprised by how few slotted screws there were. I imagine that reducing manufacturing costs was a large factor in the change.
