lot of 6 machine-age Kodaslide compartment files/photo slide cases

Estate lot of 6 mid century vintage Kodaslide Compartment Files for 2" (usually 35mm) slides. These measure about 7" x 4 1/2" x 2" high.

These files don't quite match. Three of them have a rougher industrial gray paint and are all steel. The other three have steel cases and plastic tip out trays and a hammered industrial gray finish.

One of the steel and plastic cases has some old mildew residue from storage and needs cleaning.
