Jon Mello,
I apologize for the last sentence. Anyhow, here we go. GM made 3 GM accessory fire extinguishers.
1): the first GM extinguisher was a 2 3/4 in size. The tag to the extinguisher was long. The extinguisher was dated from 08-61 to 12-61. The bottom of the extinguisher was flat, the bracket was long and clipped to the bottom.
2): The second edition of GM accessories extinguisher was similar to the first addition (mentioned above). The extinguisher was a 2 3/4 in size. The extinguisher had the same long tag. However, the bottom was round, and the bracket had a cup at the bottom. The extinguisher was also dated on top with 5-62 up And ending with a stamped 63 year.
3): The 3rd edition was from 1965-1972. The extinguisher was a little bigger, the tag was shorter and so was the bracket. However, with these extinguishers the tag had the dates of the extinguisher stamped on the tag.
NOTE: GM also made the extinguisher in 5lbs.
I have at least 8 of 61-63 extinguishers. Extremely rare extinguishers now a days and are selling for a lot of money. Very nice accessory to own and display.
