Set of two enamelled laboratory/dentist/doctor trays.

Set of two enamelled metal trays from a laboratory/dentist/doctor... 1970s-80s. I believe they come from a histology lab as the large tray has traces of paraffin (visible in the photo, can be removed when heated). The small tray has a small chip in one inner corner (visible in the first photo). White with navy blue edges. Large tray 34x25x4.5 cm, small 25x15x3 cm. Overall good condition.
