vintage Kodak film canisters containers, lot of 1930s aluminum tins full of film

Lot of six vintage Kodak film canisters - five of these have film inside.

I didn't unwind this at all, just peeked inside quick and saw the film, popped the covers right back on the containers - but since these tins have labels, I believe the film was used. One of these is dated 1931 on the label.

Five of these tins are about 1 3/4" tall, one s taller, about 2" in height. All are aluminum, embossed Kodak, showing some wear and spots - not bad considering their age.
