Actually, the first one, with the double grip screws, is most properly known as a.22/.32 Heavy Frame Target, IF it was, as I suspect, manufactured in the 1920s. It was built on the I frame, the predecessor to the J frame. S&W box instruction labels for these guns were marked .22/.32 Hand Ejector as the label was used for all I frame .22/.32 variants.
It wasn't until 1935 that S&W began advertising the .22/.32 Heavy Frame Target as the Kit Gun.
While built on the minuscule I frame, this particular model was called the Heavy Frame Target to differentiate it from the even smaller framed LadySmith (M frame) Target model.
The second gun is a K-22 Combat Masterpiece, a variant on the K-22 Masterpiece revolver built on the K frame. It became the Model 18 in 1957. As noted below, it appears to have been manufactured around 1955.
