Your Model 10-7 .38 Military & Police Tapered Barrel was manufactured in 1981.

The J frame was never chambered for a .41 caliber cartridge, it was chambered in for 32, 327, .38 & .357 caliber cartridges.
the .41 magnum was chambered on the N frame Model 57 ( adjustable sights) & Model 58 (fixed sights). I am assuming you have a a Model 57 as this came with an 8 & 3/8 inch barrel as an option.
Regardless, the AJPxxxx serial number should date it to between July & November 1985.

NY1 refers to a Model 60 with double action only manufactured for the NYPD in 1987/88. There were problems with some revolvers and they were withdrawn from service in 1988. The unsold stocks held by the NYPD were returned to S&W on June 23 1989. Officers who had purchsed the model 60 were offered a swap for a Model 64.
The unsold guns were modified and resold through commercial channels.
If there is a human silhouette target stamped on the frame near the NY-1 markings then it is a duty gun that was examined and initially passed for service before continuing problems lead to their permanent withdrawal.
A total of 3630 NY-1 marked Model 60s were made, 1353 unsold units were returned to S&W. Most fell in the serial range BAA6000 to BAA8000, as does your gun.
The info above is from the Standard catalog of S&W and was provided to the authors by RM Vivas, a gun dealer and collector in NYC.

If your gun has a serial number 180,000 then it is a .38 Military & Police Model of 1905 3rd Change manufactured between 1909 & 1915. 3 inches was not a standard barrel length however.
It's possible you have a later model 10 revolver and are quoting an assembly number, not the serial number. The serial number is found on the bottom of the grip frame, if you have aftermarket or target grips you will need to remove the grips to see the serial number. Assembly numbers were markings stamped on parts to track them in the factory, but have no meaning and are not recorded after the gun is completed.
mgbill: 1973 actually.
N1 to N99999 was assigned in 1969-1972, the N1xxxxx range was used in 1973.
