I am new to this site. I have an old cary safe made in buffalo ny . Been in the family for 60 years. Has been opened and closed many time over the years. Cannot get it to open now. Opened and closed it last week. Using the same combination that has worked for all these years. We had it drilled and opened 60 years ago by a pro. He wrote down the combination then and I still have that paper. The hole was never plugged . I just bought a digital inspection camera and can see the tumblers but have no idea what to do or what they tell me as they spin by. I also got a mechanics stethoscope but don't know what sound I am looking to hear. The safe has a 4 number combination and heres the way I have been opening it in the past but doesn't open now . 4 turns R to 65 - 3 turns L to 98 - 2 turns R to 49 - 1 turn L to 6 ...open.
The safe is 36"W 30"Deep and 40"H and has double doors. Weight a ton.
Can anyone help me . Any information will help. Thanks
