From the original documents used for clearance of A-2 specification, 94-3040, there are three contracts listed as already procured, and the spec. states in section III "All button holes shall be leather faced." I wouldn't be surprised if a collector already has a Werber 32-6225 (or Goldsmith 31-1897), since so many were re-lined and we originally thought only one contract previously existed (Security 32-485). From the original pictures we may be able to pick up the detail differences between the types, so we know where to look for identifying differences. Anyone find them yet? Please post it here. An original lined example would confirm the manufacturer, but maybe someone looked at the unlined version while restoring and already saw the internal construction differences between the makers and it just didn't register at the time. It you have two and the construction is different between the two, BINGO! Please let us know.
