Identify this style of drums and axle hubs

Looks like stud pilot hubs with inboard drums.

 

But the studs look to small for that. I bet it has inner and outer lugs ( Budd ). Very odd and I have never seen that.

 

Makes it a pain in the ### to change brakes

 

If it has std bearings, swap it to hub pilot. cheaper and 10x easier to service.

 

And they are left hand thread and short. No way they a hub piloted.

 

Something usually goes wrong when I try something like that but it would be nice.

 

I've worked on alot of different things, with a good amount of old IH experiences. Never seen this. But I have a thought. 80's they built some trucks with disc brakes. Could this be the original disk, converted back to drum?

Never seen one in person. Heard descriptions. Seen trailers converted back. Never seem the trucks in person.

Idk, this is only my thoughts.

 

Yeah, may not be possible with that one, never seen one. I have swapped plenty of budd's and spoke hubs to hub pilot on trucks and trailers.
