They didn't dump them, just moved them to the Marlin custom shop.
For the low, low, "starting price" of about 3200 bucks (US of course) you can get a brand new, custom, model 39A.
Of the the three 22's I currently own I will say, without hesitation, that my 39A (late 1950's vintage with micro groove rifling) is my least favourite and least accurate when put beside my FN Browning (Trombone) which is about the same age or my Henry pump (a couple years old)- both of which outshoot the Marlin.
So while I do like the Marlin and it functions well, I really "personally" don't see what all the fuss is about or why they command such a high resale value. I see it as just an "ok" 22.
But that's just me...
