I suspect you are somewhere in Europe!
Really very little can definitely be said based on the extremely limited information you give, but let me make a couple of guesses what you meant.
If by ".38 short shot" you mean the gun is chambered in .38 S&W, not .38 Special, then this limits the possibilities to four models.
1) .38 Double Action 3rd Model, 1884-1895
2) .38 Double Action Perfected Model, 1909-1920
3) .38 Safety Hammerless 4th Model, 1898-1907
4) .38-200 Model, ca. 1940-1945, its post WWII variant and the Model 11
The .38 DA has an exposed hammer. The .38 Hammerless has a hammer concealed within the frame. The Perfected model has a thumb operated latch like the solid frame guns, in addition to the latch on the barrel. All three of these are top-break revolvers. The .38-200 is a solid frame gun and is mechanically identical to the .38 Spl. Military and Police but chambered in .38 S&W. If your subject line is accurate it narrows things down to Item 3. Can't tell you anything more.
Pictures would help!!!!
