Think of it as a 6" model 15...

Back in the day, the model 14 was the 6" "target" 38 spl available in 6" and I think 8" barrel and came with target grips, and the model 15 was the "combat" 38 spl available in 4" and 2" barrel and came with magna grips, otherwise, virtually identical.

This particular one looks like it has had the trigger replaced or at least ground and polished. And has some gaudy grips, but looks nice otherwise.
