Need help! Do you know what these letters stand for?

This bottle is about 7and 1/2" tall by 3" diam. Has the letters embossed on one side. C& M and maybe the other letter is a long Y they are over lapped on top of each other but in a nice design, the m is over top of the c and the long y is in the middle of both. with & sign in the middle. No other markings o this bottle at all. I thought it was a citrate of magnesia bottle . And I am probably wrong. any help as to what it is would be great.

Way too small to read, can you post a clearer or at least "larger" picture? Try holding it up to the sky when you take the picture, that usually makes it easy to see the embossing.
