Hi I'm mostly a lurker here, but I thought this was neat, and cant find much about it.

I do mobile auto service by trade, live on the Monterey bay in a census designated place called Freedom, and I have a tool problem:hellobye:


Its from before the internet.
Patents from 1934 - 40. Electric model is advertised as new in '48.
I think there are models A,B,C, and D, but this isn't marked as any of them.
They also have a 'size, and I haven't found any the same, the more common electric ones don't seem to use the same labeling system.
I did find one that was inline instead of pistol grip.
It does work, is pretty quiet with a good dynamo whine when the socket isn't rattling too much.
The trigger is variable, and the knob at the back is directional control.
on trigger release it goes kerchunk and switches direction unless a load was applied, not sure if that's normal?
Love the Buck Rogers look.

It unmade a Dodge seat no problem, but balked at my 3/4 ton lugs. If I understood what I read right, the 1/2 electric was good for ~200 ft/lb.

Previous owner was a friends father and lifelong mechanic, unfortunately he was unable to take his iron with him.

Mine seems like it should be size 4u, but I swear it says 502
I did find internet mention of a 1/2 that was size 53something.

Here are the other air tools

Big gun is a 1/2 Milwaukee Pneumatic MP-141, maybe kinda harbor freightish.
anticlockwise, the Impactool

An interesting short frame impact, has a quick change drive slug(havent found any others) and no markings, anyone know the make? I like feel.

Skil model 1002 hammer. military? inventory number, and possibly service/inspection stamps starting with '53

Center gasket scraper, no brand, has a part number with no internet match.

Bottom air rat, I don't know that marking

Skil 1004 ...2" longer than a 1002 I guess, about the same stampings

Another short impact, very similar to the other, some CP and Rockwell look more like this.

And last a Rodac II 2000 RPM drill, very aerodynamic.

All worked right off the bat.

Name me?

Cool collection!

If the I.R. impact wrench has a 3/8ths drive it probably won't remove those Dodge lug nuts. I have a '95 Dodge Cummins 2500, and the lug nut torque is 135 ft. lbs.

And what's a "census designated place called Freedom"?

Got to love the old tool ads where they advertised one tool to do a multitude of tasks. 3/4 ton lugs *IF PROPERLY TIGHTENED and not corroded can be a chore for even modern 3/8 impacts, my hot shot MG325 will do them but it works pretty hard. I wouldn't be too disappointed if that old 3/8" won't. Lube it up and feed it proper pressure.

A CDP has a name and post office, but doesn't have an administration like a town or city. City of Watsonville is 4 minutes away.

I wasn't surprised about not pulling lugs either, mostly just wanted to hear it work on something it would not do, and they were handy.
