Vintage metal cabinet ID

Yesterday, I also scored this awesome metal cabinet locally for free. It's unfortunately missing one drawer, so I'll have to make one, but it's cool and the price was right.
It looks like it had a tag in the top center that has broken off, so I'm unsure of manufacturer.
Does anyone recognize it?

 

I don't know anything about it but I think it deserves a definte clean-up or resto,
forgetting about the leave-it-as-is patina business.

 

It was in a kitchen. Center top doesn’t and never did open.

 

Looks like it was an old Eljer sink and cabinet.

 

Here’s my Youngstown Kitchens

 

The kitchen cabinets came later but the parent firm was the Mullins Manufacturing Company, the group that introduced the Mullins trailer in 1936.

 

I think I paid 1$ 20 years ago at an auction took me 10 years to finely sandblast and paint (ford grey tractor paint) but I think I’d rather have the trailer
