Gunbroker

I recently bought a 4" Model 14-2 on Gunbroker. I just wanted a good shooter but I may have gotten a very rare gun fairly cheaply. Someone told me that only 2038 of these were specially made for a huge gun store in Ohio during the mid-sixties. Is this one of them and is it worth more than the $400 it cost me? Thanks for any help.

PS: I've attached pictures, one of which includes the serial and model numbers.

PPS: Whoever is IDing the S&Ws here is a godsend. My hat is off to you!
