To both new posters, welcome to the forum. It's like family!
First, the model 14, could be early 80s to 1991, perhaps? Not much difference from the ones coming out of the shop today.
Dwight, your model 5 should be about 1959 to 61, I lean more towards 59 than 61 because in spite of the shallow choils, they still have the sharp "fishook" turn, which became more tapered out in 62, 63, etc. The sheaths' retainer strap and randall stamp date the sheath 59 to 62. Very nice knives. Thanks for your service!
