If the recipe was from the 1960s and 1970s, it was probably a 10 oz. bottle. If earlier, maybe an 8 oz. bottle? I don't see any collectible bottles that are smaller than 10 oz.

Hope this helps.

I tought thee arly bottles were 6 oz?
What's the recipe? maybe that will give a clue...if it's for something like a marinade,2 oz one way or the other won't matter a bit but in a cake it sure will!

Below is one from the 50's that was 7 oz.

Here is a link that might be useful: 7-Up bottle

Duh! Now I remember!...That's why it was called 7-up!

I thought I remembered a smaller bottle! Like the little bottles of Coke that my mom used to love.

They most definitely were seven ounces.

Thanks everyone. I thought it might be 6 oz. too. The recipe is one my Mom made in the 60's. I need to bring cool desserts on a camping trip. I hope you enjoy it. It's so easy. It's easy to see why I go by Gram. :)

Lime Delight

1 1/4 c. graham cracker crumbs
3 TBS. sugar
1/3 c. melted butter

Combine crumbs & sugar in pie pan. Stir in melted butter. Pack in 9" pan, pressing firmly into bottom & sides. Bake at 350° for 8 min. Chill & fill.

Lime Filling
1 small bottle of 7-Up
3 oz. pkg. Lime Jell-O
1 pint vanilla ice cream

Heat 7-Up to boiling. Take off heat & dissolve Jell-O in pop. Add ice cream & stir until melted. Pour into crust & refrigerate until firm.

There are several on E-bay for sale and they are 7oz. I also found a picture of one from c 1930 that is 7.
