One of the SWHF officers may be along shortly, but my understanding and personal experience is that information such as a ship date and destination are almost universally available for every S & W firearm since 1857, and this is found in the letter of authenticity.

The "records" that are only available up to 1967 are extra documentation that might be uncovered with the "deep dive" search, such as correspondence about specific guns, service records or shipping invoices.
