My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com

  1. Some wafer locks have anti-pick notches in the sides. These will act the same as serrated pins. That would explain the feedback and counterrotation you mentioned.

  2. Here is what I found out about the ball bearings:
    You will find a ball bearing at the bottom of pin stacks in some or all chambers of Corbin and Russwin cylinders manufactured from about 1902 until the mid 1960s. The oldest cylinders have the ball in every chamber. The number of balls was gradually reduced until only the front two chambers had them. The purpose of the balls was to reduce wear on the pins. As harder brass brass became available, wear became less of a factor, so the usage of balls in the pin stacks was eventually phased out.*
    Now you know how old the Russwin locks are also.

  3. Great pickin' again as usual Bill ! I would love to see yu gut that old Russwin and like to see what the pins with the ballbearings look like and how it is set up inside ????

  4. Actually  I think ball bearings were used to "prevent" drilling but I'll have to confirm that. I have two of those Corbin padlocks right here, no keys yet. On some wafer locks the wafers are staggered a little.  The pancake lock s really nice.
