Technical Mystery i-beam axle: Can you identify ?

I picked this up recently for nothing because I thought it was interesting, but have searched the web for many of the common US auto manufacturers circa 1920-1940 and couldn't find anything even similar.
Other than the unique dip in the center of the axle, which should help greatly in identifying it, note that it apparently used a single transverse spring, NOT semi-ellipticals (no large pads on the axle) with spring perch holes 35-1/2" apart, the top of the kingpins are 50-1/2" apart, and the forging is 1-3/4" wide, looking down from the top. BTY, it's beefy as hell, much like my '32 heavy axle. Two pics of it are attached.
Any help would be greatly appreciated !

 

Is that old chrome or just bright steel on the high spots? Cool axle - looks like a dropped Model A or 32 (through 36) with some custom flair and those dimensions match those pretty closely.

Are your measurements center to center of the holes? The dip in the middle would shorten the axle just a smidge if you were measuring straight across.

 

I think that is a ‘46-‘48 Lincoln axle, check the diameter of the king pin holes, early Ford is .813, Lincoln is .936

 

Here is a Lincoln on eBay for reference. Harder to find pictures of these than of Fords.

 

I'm not seeing any tweaks from having camber set that you see on some I beams and those bends in the middle seem to match.

 

From the angle of the king pin holes, it looks like wall art.

 

Hmmm, that bend doesn't look intentional... like it was mangled and straightened at some point. Here's a pic of a 37-41 Lincoln axle, ad says 52" KP to KP but no perch measurement.

 

Heres a Lincoln axle i had 20 odd years ago.

 

Check Anson Axles On Instagram. He has several pictures of Lincoln axles he's worked on.

 

The OP's axle in question doesn't look like any of the Lincoln axles posted as the Lincolns all have a flat center section that angles upward on both sides. The Lincoln axle 34 Gaz posted has much different shaped webbing section between the spring perch and kingpin.

I agree with Dan Hay, that it's an unintentional ben (damage) vs a purposely dipped axle. Look at the pic Mr48 Cev posted; the dip is not centered. It's slightly off-center to the left.

 

Also every Lincoln axle that has been posted has a raised pad inboard of the perches which this axle does not have. I still think it is a dropped Model A or 32.

As is, the camber would be crazy with a regular Ford spindle so I also think the bend is damage and not style…

 

IIRC, the kingpin inclination on Lincoln axles is different than that on ford axles.

 

The k/p holes will tell the story.

 

Looks like a Lincoln to me, if so, I believe the inclination of the spindles will differ from the Ford, not sure how compatible it might be, but then anything is possible with proper tweaking.

 

I just looked at Anson's Instagram page and the axles he claims are Lincoln do not have any pads?

 

Thanks very much for the info - the seller of the axle and most of the replies here point in the direction of a Lincoln axle, but I believe your assessment is closer. To answer your questions, the axle isn't chromed, the hole to hole dims I stated are centerline to centerline, but the most telling dim are the kingpin holes. They mike out at .997-1.000. Was your note about big trucks having 15/16" and 1" kingpins referring to Ford big trucks or other makes? Got any idea what models of big trucks have those kingpins? I looked at AA's earlier, but they seem to be the same as cars.

 

Thanks - kingpin holes mike out at .997-1.000. Would that be some kind of big truck?

 

I am having trouble finding specific information and don’t have the personal experience to weigh in, but may be prewar/wartime 1-1.5 ton truck?

 

IDK, but that is very likely. As mentioned by @trevorsworth I could’nt find k/p specs on large early Ford trucks either.
