Need some with an ID on my father-in-law's S&W.It's a 38 S&W Special CTG. The serial # is 998954 on the butt and on the bottom of the barrel.On the cylinder assembly is #87994. the left side wooden grip has 2 sets of #'s 995 and 445 on the inside.The gun was past on from his father to him in the early 60's. In the early 70,s he flared the barrel with a bad hand load. It's been in a bag until last fall.For x-mas i took it to a gunsmith and had it checked and reblued, the barrel shortened from 6" to 4" and put a front site on. I am interested in it's history.. Thank you for any info...
