To make an extended story just lengthy, i did handle to get it open once more by trial and error. I now have the lock apart and https://www.mixcloud.com/safelocks/ am planning on cleansing it up and reassembling it. From photos on the S & B site, it seems to be an 8400 model with the twist lock on the dial. I'm fairly well versed with hand tools, and have taken apart a lot of stuff and am confident that I will get it again together correctly. I have it soaking in water, and a few dish detergent in the mean time as i lack an ultrasonic cleaner. Once i get it good and dry, can somebody inform me roughly the place and what to use? Please do be particular, it had a yellowish brown waxy grease in it when i opened it up. Any advice and strategies vastly appreciated. Will even give my quantity to anyone keen to talk me by it and compensate in your time.
