Vintage Darkroom Photography Developing Trays (Set of 3)

We believe these are from the late 1950s, when our mother was really getting into photography. One is purpose made enamelware – the small Cesco Acid-Resistant Photographic-Tray (Made in Columbia) with corner draining spout and a size of approx. 8x6” inside. The other two – a Vollrath Special Blue of 15x11 and an unbranded tray of 17x12– are also enamelware which were commonly used in photographic developing. 
 
Enamelware’s smooth, nonreactive, durable surface was easy to clean and resists chemical reactions, making them ideal for holding processing solutions in a darkroom. 
 
The two non-purpose-made trays were also used for baking at the time, but should not be used for baking in this day and age due to glazes containing lead and cadmium and the possibility of lead leaking if there is a crack in the enamel.
 
These seem to be in good vintage condition, although there is some glaze missing on the Cesco and the largest tray has spider web like cracks in all four corners. See photos.
