Set of two enameled laboratory/dentist/doctor trays

Set of two enameled laboratory/dentist/doctor sheet metal trays... 1970s-80s. I think they come from a histology laboratory because the large tray has traces of paraffin (visible in the photo, can be removed when hot). The small tray has a small chip in an interior corner. (visible in the first photo) white and navy blue borders. Large tray 34x25x4.5 cm, small 25x15x3cm. Good condition.
