Old Kodak 35mm metal film cannisters?

I also have some (red cap/yellow can, Kodachrome, brown/yellow, Plus X, blue/yellow, Ektrachrome (I think)). I also have an all silver. Does anyone know the whole color system?

somewhere in the beginning 70s i think - when i started photography then, kodachrome II was sold in metal-silvery canisters, so they were available there. kodachrome 25 came in plastic canisters

I agree with Harry; the very earliest 35 mm film I purchased (Plus-X and Kodacolor) in around 1973 came in metal cans, but by the time I got back to 35 mm after a short affair with MF (around 1976 or so) the film was coming in plastic cans.

I used to buy Agfachrome 64 in lightweight aluminum containers up to about 1980 or so. I still have a few left -- the containers, not the film.

Before 1974, Kodak b/w film came in foil packets, color in the aluminum cans. After that, the plastic canister became standard. Cheaper and recyclable. It's probable that the color-coding matched Kodak's color codes for their film types, e.g. blue for Ektachrome, black foe Kodacolor, etc.

Those were pretty nice in that the color combinations (blue, red, yellow, white, and aluminum) told you what you had without having to closely examine the cartridge. (I still have some of these around, but don't remember the color codes.)

I inherited a a bunch of them -- sold some on ebay for an amazing price. I have a pretty good collection, including some for 120, sold by Agfa, I think.

What film came in the yellow with green caps? It's either B&W or slide, not color print. My Dad's stuff from the 1950's. Probably Kodachrome since the slides are still almost perfect.

Thanks for all the replies! I wish I knew the color code also. I would like to have one of each....So early 1970's is when they stopped making metal cans, I guess I should have asked when did they START making the cans also? What came before the cans? Foil or paper wrappers? thanks Rob
