Welcome to The High Road.
I think your revolver is identical to one I identified in post #139 in this thread, so I'll repeat myself.
I think you have a Smith & Wesson .32 Safety Hammerless, 2nd. Model. They were made between 1902 and 1909, within a serial number range running from 91,418 to about 170,000. No. 134,662 was probably made around 1905 give or take a couple of years.
These were very popular pocket revolvers because that checkered piece you see on the back of the handle is a grip safety that has to be squeezed in before the trigger is pulled. The feature made accidental discharges almost impossible, and it was also advertised as an additional safety if small children were around. Standard barrel lengths were 3 and 3 1/2 inches, but special lengths ran from 2 to 6 inches. The stocks are mother of pearl, and if they have a gold colored S&W medalion at the top they're genuine S&W stocks and worth somewhat more then others. Standard finishes were full blue or nickel plate with a blued barrel latch and trigger guard. The trigger was color case-hardened.
The patent dates on top of the barrel are: Feb. 20 1887, Dec. 18, 1887, May 11, 1880, Sept. 11, 1883, Oct. 2, 1883, Aug. 4, 1885.
The 5-shot cylinder is chambered in .32 S&W. Ammunition is around but difficult to find. Given the revolvers age it might not be a good idea to shoot it.
Production started in 1888 and the gun was so well liked it continued in S&W's catalog until 1937.
Given this gun's history, I suggest that you get it "lettered." To do so you will need a snapshot of the gun, a full description including the serial number on the butt, and a check in the amount of $30.00 made out to Smith & Wesson. In exchange the company's historian, Roy G. Jinks, will research the original records (which are not computerized by the way) and send you a letter containing the details of what he finds.
This comprehensive document will contain an overview of the model’s history, followed by the details of your particular gun. This usually includes the caliber, barrel length, finish, and the exact date it was shipped from the factory, and to what distributor or dealer. If there are any special features they will be listed too. This information is often invaluable to both you and future generations.
