Found a nice bottle dump today.

Buster, Paul's started in 1917. I wouldn't call their early bottles art-deco, but just heavily embossed. They switched out by 1930 to clear and slightly different bottles. I have been talking with an expert on another site for glass maker's marks, and neither of us have as of yet discovered much on C. P. Co. other than one company, which likely didn't make this bottle. It should date to the '50s or '60s, but if what you're saying is possible, my bottle, albeit incredibly unlikely, might be 1930s and could fit in with the date of Charles Pfizer Company, as they seem to have changed names to Pfizer by 1950, likely sooner (if what I found is correct.) If it hadn't been for the fact I was curious on the company, this plain little bottle would have sat as an unknown mystery forever.
As for the house, I don't think it goes back before 1950. Who knows, though: maybe another older bottle dump is on the other side of it? As for getting back to it, not likely this month as I'm in high school and kept busy. Maybe one weekend, but I don't know. Currently the house is up for sale. So who knows what the new owners will do when they find the dump.
Click here to see an older thread I did on Paul's. Thanks for taking interest in my thread. As it's a pretty modern dump, many here I am sure would find only light interest.
Here is the bottle from or for C. P. Co.-- anyone know what it might have held?

I'd guess that C.P. Co. is Colgate Palmolive Company.

Closest thing to the Truth since research started--mystery solved? This one doesn't look like any of their vintage bottles.

Looks like a shampoo bottle .

Seems too small--I found an ACL shampoo, as I think I showed. Unless it were trial- or travel-size. But, by the looks of things, they didn't do much travel. And, unless it were free, they probably stuck with the stuff they normally bought. Like Lustercreme.

I've dug shampoos that small. Dozens and dozens in one hole. Behind a 1950s house lol

Me too reach!!! And dish soap! It seems back in the day everything was packaged smaller. 6 ounces of Coke???? That's only 2/3 of a cup lol.Lisa

Well, then it' likely either shampoo or dishsoap. Now we need to find either a photo or a diagram of this bottle that proves it.
Thanks all! []

I am searching images of shampoo bottles and I found a few with screw tops consistent with yours bear but haven't come up with an exact match.
