houston york safe combination

I bought an old, very heavy safe (railroad safe) that when I bought it supposedly had combinations from his grandfather. Since I have paid for it, the move, and the outer door cracked, I Now need help on the inner combination for a upper cash box. Luckily the cash vault was open and I was able to take apart the works to get that code tonight. I only have two doors locked, one being a two key box that only has the client key tumbler (that I have the key for) and the above combination box. I read somewhere that York Houston went out of business some time ago but would anyone have records or would you have any suggestions for me. I would really appreciate any help. THANKS, Mark
