Posted 10 Months, 3 Weeks ago Brian Sallur Senior Boarder Posts: 40   I have an old stock certificate from a Delaware Oil Company called Shallow Oil, Inc. Does anyone have any suggestions on how I might research the certificate? It's from the year 1938. Any Help Greatly Appreciated! The administrator has disabled public write access.

Yours sounds better than the Old West mining stocks a friend gave me a few years ago. The administrator has disabled public write access.
