Diebold Special

Hi I just inherited a Diebold Safe and have some issues with it. Diebold's Special Canton,O. Below that there seems to be a hand paited picture of tree's ect... Its a single door with a dial and handle and is also on 4 wheels My issue is that i dont have the combination. I was provided with one but not sure what sequence, left to right how many turns between numbers ect. I can not gurantee that it is the correct combination. Any help would be greatly appreciated, age, combination sequence or someone in Toronto Canada that can have a look at this. If you need pictures i can send them. Thanks Tdn
