The Model 52 was a great, possibly the greatest, of the centerfire target autos. It was the victim of dropping interest in formal target shooting and the changeover by police to the 9mm. The 952, essentially the same gun but in 9mm, is (AFAIK) still being made.
Previously owned Model 52s bring a nice price today, around $1000 in top condition.
For those wanting a .38 Special auto, though, please note that the Model 52 was designed for and works only with flush seated wadcutters; suggested loads are in the range of 2.5-2.7 grains of Bullseye. Loads with standard bullets won't even fit in the magazine.
