I purchased 170 shares of Groundstar Petroleums Ltd (N.P.L.) from Canarim Investment Corporation Ltd. in October 1973. Any value?
Robert, from the information I have available, the company has had numerous name changes and at least 3 reverse splits (1 for 5, 1 for 9, and 1 for 10) and is now Cypress Development Corp, which trades for about 12 cents per share. But, due to the reverse splits, your original 170 shares were almost certainly wiped out. You can confirm this information with the current transfer agent, Computershare (www.computershare.com).
