I have a S&W New Depature .32 Concealed hammer top break 3inch barrel nickel finish revolver . Ser #22792 followed by a star. Looking for the year it was made.

Who made this? You need a mfr name to get started.

If it saw service with the British it will be a Webley.

Decoding H&R serial numbers is not easy and it takes up quite a bit of the H&R book as different models usually have seperate serial number series. gererally speaking there were three types of serial number series.
Pre 1905 (1904 and before) which were more like batch numbers and usually ran from 1 to 99,999. on some models there was a different series every year.
Post 1904 (1905 to 1939) one single series starting at 1 and going into the middle 6 digits (some third model auto-ejecting revolvers have been observed with number in the 800,000 range.
Ift here does not look like there are any markings on the left side of the barrel other than the caliber this would be the premier model fitted with extra cost oversize grips and 6 inch barrel. during the same time (1925-1934)frame H&R offered this revolver as the H&R TARGET (aka model 766) the only difference was H&R Target was marked on the barrel. by the time the premier model was fitted with a longer barrel and oversize grips the cost was about the same for the two models. the offering of the H&R Target model was just another way to try to sell more revolver. factory serial numbers are not available for this model so i believe this revolver was manufactured before the H&R Target was introduced in 1924 (most likely 1920 to 1923)
below is information of both models.

H&R PREMER SECOND MODEL SMALL FRAME TOP BREAK R.F. & C.F. ----------1905-1941

There has not been enough data gathered on serial number to try to come up with a serial number range for the different variations.
First Variation, model name & caliber marked on left side of barrel, patent dates 5-14-89, 4-2-95, 4-7-96---------------1905-Only
Second Variation, model name & caliber marked on left side of barrel, patent dates 4-2-95, 4-7-96-------------------1906-1908
Third Variation, caliber only marked on left side of barrel, patent date 10-8-95-------1909-1913
Fourth Variation, caliber only marked on left side of barrel, no patent date, state not spelled out in address (MASS)---------1914-1915
Fifth Variation, caliber only marked on left side of barrel same as 4th except different font used in barrel markings----------1914-1915
Sixth Variation, caliber only marked on left side of barrel. State name in barrel marking spelled out (MASSACHUSETTS)-----1916-1924
Seventh Variation, new grip frame, there is no step down for the grip panels to fit into-----1925-1942
After 1930 listed in catalogs as; PREMIER No. 30 .22 Rimfire 7 shot & PREMIER No. 35.32 S&W 5 shot
VALUE: 100%=$265 60%=$75 Add 10% premium for blue finish; 20% premium 4", 5" or 6" barrel; 20% premium for 22 rimfire caliber; 10% premium for 7th variation
If this is a top break it is a H&R Premier model manufactured in the 1924 to 1930 era or one of its variations. if it is a solid frame model it is a model 1906 or one of its variations manufactured in the 1932 to 1937 era. without a picture or knowning the exact markings i can't give you an exact model.
1940 and after letter codes used to denote year of manufacture. starting with A in 1940 and going to BC in 1986.
Caliber markings on the side of the barrel ALWAYS indicate 1905 or after manufacture. when H&R made the switch to smokeless powder in 1905 they started marking the caliber on the left side of the barrel of all their handguns. no caliber markings = black powder, caliber markings = smokeless powder.
Please keep in mind that H&R did not always obey their own rules and there are exception to every rule. during 1890 though 1904 H&R was manufacturing so many top break revolvers they starting using a letter code after 100,000 had been reached. these letter code were stamped along with the serial number on the bottom of the top strap (the cylinder had to be removed to see this location).
Hammerless Bicycle models (1899-1920). the caliber markings and 6 digit serial number indicate it is a second model and if in good condition it should be safe with modern ammo. the bicycle hammerless (small frame, 2 inch barrel) is serial numbered in the same series as the regular small frame hammerless model.

iver johnson single barrel champion shotguns with a single letter suffix to the serial number were manufactured between 1920 and 1929. it seem that most of the 410 were used quite a bit and very few are in excellent condition. the original finish was an oil finished stock, browned barrel and case hardened frame.

CHAMPION MODEL 36--------------------------------1909-1922
Single barrel; rebounding center mounted hammer; top lever operated break open design; gauges: 12, 16, and 20; barrel length: 28, 30, and 32 inches (features barrel and lug forged in one piece) bored full chock only; American black Walnut but* stock and fore-end; automatic extractors; weight 6¾ pounds; overall length with 30 inch barrel 45 inches; case hardened receiver (nickel available as option), browned barrel; automatic ejectors extra cost option; .410 bore, 24 and 28 gauges offered in 1913; 24 gauge dropped 1928; all gauges except 12 dropped after 1941; name changed to Champion single Barrel in 1917.
CHAMPION SINGLE BARREL---------------------------1923-1978
This is the same gun as the earlier Model 36 champion except that the smaller gauges are now built on the same frame as the large gagues. See above picture for specifications. The exact year production stopped has not yet been determined. Some of these single barrel shotguns have been seen with Canadian marking, these were most likely shipped to Canada and then marked as there is no evidence that Iver Johnson's Arms & Cycle Works ever had a manufacturing factory in Canada
