* 1961-1980
The Model 16 was never made in 357.
1892 Winchesters were not made in 357
The Smith and Wesson model 19-5 was made from 1982-1987.
The model 26 was in .45 acp, NOT .357. They were made from 1950 until 1966. So, to answer your question, there is no value in something that doesn't exist (a S&W 357 Model 26).
There is no S&W with that Model number.
I can say that your smith and Wesson model 15-2 .357 magnum was made between the years 1961-1966.
Uberti made a .357 derringer under the Maverick model name. I know of no other 357 Maverick. Intercontinental Arms was the importer of these to the US.
The model 26 was in .45 acp, NOT .357. They were made from 1950 until 1966. So, to answer your question, there is no value in something that doesn't exist (a S&W 357 Model 26).
No Model 27 has that serial number.
