I have a American Eagle gun safe that was replace with a new one when my house was flooded foe Issac. I haven't worked the dial combination in a good while. I did that tonite and we'll I forgot the combination so it's open with the rams in the closed position. I called Cannon and they don't keep the combinations but for one year. I don't have any paper work for the as that was thrown away. My question is, what is the best way to retrieve the combinations.
