Vintage shelf brackets

OK, I have these brackets that I pulled from an old medical/dental cabinet that was in the basement of a mortuary I lived/worked at in the '90s. This cabinet was old and these brackets held glass shelves. They were tossing it out and I wanted it so bad but had no room, so they let me pull the brackets. I am now going crazy trying to find a picture of a cabinet like that. The shelves were like steps. Small at the top and larger at the bottom. Hard to explain lol Here are the pictures of the brackets. Can anyone find the cabinet? lol

 

Nice - Damn, I'd a loved to see you get the glass shelves too!!!!!!!!

 

Yeah, tell me about it lol I knew I wouldn't have been able to keep them safe.

 

Something like this where the lower section had deeper shelves?

 

Or more like this where they were all in one cabinet?
