Durant Motors shares converted to Dominion Motors Shares

This wasn't the best investment my Great Grandfather made! 5 shares of Durant Motors Company originally valued at $50.00 in 1922 by 1944 value=$0. Eventually continued in Canada as Dominion Motors after Durant closed up shop in USA. Eventually that company was shut down as you can see by the letter.

Here are a couple links; this company had an interesting history!
