Mr.B -- Your pastors Puma White Hunter is 1956-1964. The White hunter was developed in 1956 and I have it stuck in my mind they were introduced in 1957 but, as always, I could be wrong about that last. Edit: Puma Knives were first imported into the U.S. in 1957 by Kurt Gutmann, founder of Gutmann Cutlery Inc.
In the last quarter of 1965 Puma introduced the numbered date code system and most Pumas since then have a date code stamped on it somewhere.
As for value, there is currently a White Hunter on eBay with the same scabbard, with paperwork, with the same box and in the same excellent condition as your pastor's knife. It has just over a day to go and it's currently at $570. Another without the box and paperwork is at $330. You know how it is. Depends on the day and who's buying.
Sorry, I can't help you with the folder.
