Usually there are one or two for sale somewhere but strangely right now there are several available. Look at guns international.com and you can judge for yourself where yours falls.
You can see quite a few on GB as well, at least yours still has the 2 piece box, and most likely steel follower mags. The later 52-2s with 3 letter prefix do not have as nice a finish, but I have seen them still sell at crazy prices. Best of luck, it should do well.
