The stocks on your gun are not period correct as they do not have the diamond center, which was eliminated ca. 1968. The Model of 1950 ended production in 1961. Depending on when your gun was manufactured, the correct diamond magna stocks would be either sharp shoulder or rounded shoulder, both with the center diamond. Sharp shoulder stocks were in use from right after WWII to around 1952 when the shoulders were rounded off. A nice set of sharp shouldered stocks will not be cheap, probably in the neighborhood of $250 or more.
Below is a pic showing the two different styles, round on the left, sharp on the right. To complicate this a bit, there are two different types of sharp shoulder magna stocks. The early post war N frame butts were slightly longer than the later ones. Thus, the magna stocks were also slightly different in length. IIRC, the break in the length occurred around serial # S72000. That serial # would be prior to any Model of 1950, but if you were only looking for sharp shoulder stocks, you could possibly end up with a set that is slightly too long for your butt frame. If that should be the case, please do NOT sand them down to fit. They are worth considerably more than the shorter version stocks.
There were only 2,768 Model of 1950 produced, making them somewhat scarce. If the rest of the gun is as nice as the left side shown in your pic, with correct stocks, I would think the value would be much closer to $2000.
Here is my Model of 1950 shooter that I purchased three years ago for $1100. I thought it was a good deal then, and I still do.
