Zee First Aid Kit Large Wall Hanging Set Industrial

Zee Medical Products is still around but no longer headquarted in Downey, CA. Downey is a suburb of Los Angeles. No longer available also are the solid metal cases like these. Now they are made of durable plastic.
As can be seen it is well stocked with medical supplies. It has probably been stocked a restocked a few times are from the 1960s or perhaps 70s. No UPC codes on these. They are from the Rotaco company in El Cajon, CA which seems to be long defunct.
Bought this at an antique mall in the high desert along Route 66. It had been kept outside and was a tad dirty but cleaned up well.
