Weird markings on bottle

[mshlbelle]

We found this bottle at Norris Lake in Tennessee when we were cave exploring. Does anybody have any idea what kind of bottle it is? I can't figure out the markings on the bottom. Reminds me of a syrup bottle, but we have no idea.

I think it's an Oil bottle, Wesson or some other 1950-60's product, or a cleanser like Top Job. I know that form I just can't nail it down...

Or Mrs. Butterworth's pancake syrup? Can't read the bottom at all, alas. Yak
