rnunnalle,
For informational purposes, here is a little dissertation that I wrote on the K frame target masterpiece series of which the K-32 is a part:
The Masterpiece Series began on 1/25/1940 with the production of the K-22 Masterpiece, now called the 2nd Model. War time delayed any further production of target guns until the first redesigned K target model (K-22) of the Masterpiece Series was introduced on 12/13/1946. The redesigned Masterpiece Series guns sported a ribbed barrel, the new micrometer click sight, anti backlash trigger, short cocking action, six groove tangs, serrated trigger and a 1/8” or 1/10” Patridge front sight. In its advertising, Smith & Wesson emphasized the name “Masterpiece.” They believed they had introduced a true masterpiece for the competitive shooter. On 6/09/1947 the K-32 and K-38 became available. The weight of the three different caliber guns varied with the K-22 at 38 1/2oz, K-32 at 36 3/4oz and K-38 at 36oz. As a result of the requests from the target shooting community, by 04/10/1950 the weights were standardized at 38 1/2oz. (loaded). Beginning in 1957 the K-22 was assigned the designation of Model 17, the K-32 became the Model 16 and the K-38 became the Model 14. Sales of the Model 17 and 14 have always remained strong but the Model 16 was never as popular. Only 3630 K-32s were manufactured between 1947 and 1973 when it was dropped from production.
As you can see, any K-32 is relatively rare. In the event that your model 16-2 is 98-99% and has the original box, paperwork and tools I would value it at $1600.00 - $1750.00. If it was a very rare Combat Masterpiece with a 4" barrel - that is another story.
Hope this helps.
