There are a couple of variants of the model 14 (AKA K-38), the most interesting being the 6" Single Action Only (yep, you have to cock it each time) target model. The first generation K-38 was made until 1981.
A 98% gun is worth ~$250 the SAO about $275.
The newer Model 14 K-38 Combat MAsterpiece is worth about $50 more. It's effectively a Model 19 in 38 special. They were made until 1999
