Sentry Safe - no combo

[77luke]

I just got a sentry safe today from a pawn shop for $30. It has no combo and I don't know what the model is. Does anyone have any pointers (without breaking the rules) on figuring out the combo?

Mods, just delete this if it shouldn't be posted.

I think you knew before you posted that this isnt alloowed in the public sections,

The best i can suggest before locking it is to read up on how stuff works and then matt blazes article on manipulation,

Theres no easy way and certainly no ways that can be discussed here,
