Smith & Wesson “Lemon Squeezer” .38 Safety Hammerless model
Based on the shape of the barrel latch, what we have here is a .38 Safety Hammerless model, a.k.a "Lemon Squeezer". Smith&Wesson issued 5 different variants of the .38 and 3 of the .32 caliber. There are only small variations, though.
The Safety Hammerless revolvers were the last of the topbreak series and come immediately before the Hand Ejector model with swing-out cylinder.
Production started in 1886 and the very last of these revolvers left the factory in 1940, long after production was resumed. The 3rd Model was introduced in 1890 at approx. serial# 42484 and was produced until 1898 (highest known serial# is 116002).
Your revolver is interesting because it is equipped with the quite scarce 6" barrel. Most of the production feature shorter barrels, the 2" one being nicknamed "Bicycle Model".
Technically, those revolvers were quite advanced because they included an "inertia-type" firing pin, developed by Joe Wesson, son of Daniel B. This type of firing pin was mounted in the frame and spring-loaded. It could only hit the primer upon receiving a sufficient blow from the hammer, which transferred the momentum from the hammer to the firing pin itself. When the concealed hammer was at rest against the firing pin, the pin would not protrude through the frame.
I don't know who invented the system at first, but it wasn't Joe Wesson anyway. The "inertia-type" firing pins were at the same period already in use in the Belgian Leclercq shotguns, and probably in numerous other weapons.

Smith&Wesson Safety Hammerless “Lemon Squeeze”
This revolver is a .38 caliber double-action Smith&Wesson Safety Hammerless, issued between 1898 and 1907 and also known as the "lemon squeeze" due to the safety catch protruding at the rear of the grip frame. Collectors have distingue 5 models in this serial, all with minor variations. The conventional top-break barrel latch identifies it as the Fourth Model, made from 1898 to 1907. The serial numbers in this popular model started at 116.003 and ended with serial# 220.000. It was available in blue or nickel finish and was offered in a wide range of barrel lengths, form 2 to 6 inch.
Interesting and relatively inexpensive model. Still easily available today in perfect condition and in original cardboard box.
The company also issued the same model in the .32 caliber.
