hi, great forum. i just bought a model 36 with serial # AFJ2170. would someone please tell me the manufacture date. thank you. i was in the gun shop ready to buy a new five shot small ruger that locked up real nice and tite when i noticed the 36 on the used shelf. locks up real tite and came with original grips, rubber grips, speed loader and original box, also had the aluminum cleaning rod with brass brush in unopened plastic. appears almost new. i was so lucky.
