One Gallon Cream/Butter Churn offers Top Milk Bottle

This bottle is offers one gallon with a cream/butter churn top. Wire handle is not on it. From the marks I know it is Illinois Glass Company. I am learning about bottle marks so please bear with me. I am inclined to believe this bottle is from 1948. It is 11 1/2 by 6 inches. Would make a great vase in a country kitchen!

Marks on the Bottom are as follows:
Left 7
Center Circle with a diamond through it the middle has a capital I
Right 9
Below is a 5

Separate section reads:
SCS - 48
CCS - W

I was drawn to this because of a story involving my boyfriends grandmother. She use to skim the fat that rose to the top. Freeze it like Ice Cream and eat it with Hershey's Syrup.
