I don't think anyone is making reproductions of double action S&W top brakes only the single action versions.
Howdy
That is correct. The only replicas of the S&W Top Break revolvers being made today are single actions, like the Schofield, Russian, New Model Number Three, and most recently the American model.
I am pretty sure nobody ever made replicas of the S&W double action Top Breaks, of which there were plenty.
Here is a pair of 44 Double Actions. The top one is a target model, the bottom one is a standard model. This model was available chambered for 44 Russian, 44-40, and 38-40. The most common was 44 Russian, which is the chambereing for this pair. The 38-40s were quite rare, only 276 were ever made.
The five shot 38 Double Actions were styled very similar to the 44s, except they were five shooters instead of six shooters. Chambering was 38S&W. (Not 38 Special). This one is a 38 Double Action, 3rd Model.
The 32 Double Actions had the same styling, but they were smaller still. At the top of the photo is a 38 Double Action, 4th Model. At the bottom is a 32 Double Action, 4th Model, chambered for 32 S&W. (Not 32 S&W Long).
The Safety Hammerless models were double action only. Sometimes known as lemon squeezers because of the grip safety. This is a 38 Safety Hammerless 2nd Model, chambered for 38 S&W.
This is a 32 Safety Hammerless, chambered for 32 S&W.
The Bicycle Guns were Safety Hammerless revolvers with 2" barrels. Perfect for protecting Daisy against ruffians that might be encountered while on a bicycle built for two. As can be seen on the barrel, this one is chambered for 32S&W. There are lots of fakes of these out there, the real ones had the caliber marking centered on the barrel like this.
The last Top Break revolvers that S&W made were the Perfecteds. Made from 1909 until 1920. Five shot 38S&W, double action or single action. These were the only top Breaks S&W made with the trigger guard integral with the frame. Tricky because you have to remember to lift the latch at the top at the same time as you push the thumb piece forward to open them for loading. I always have to remember every time I pick one up.
