Continental Distilling Corporation Glass Bottle Philadelphia, Pa

I found this bottle some 20 years ago in the woods behind my childhood home.  I have identified it as a glass alcholic bottle from Continental Distilling Co. in Philadelphia,Pa.  The bottle is intact (no cracks), but has minor rust on the cap and a minor scratch in the glass on the back that are hard to see. It also has some mineral deposits.  Sold as-is.  I am not a bottle collector, but wanted to make this available for anyone who does collect bottles. Please let me know if you have any questions. It has the markings "D 18","12-5"," and "34" on the bottom.  I am not sure what they mean.
