Nice opening act. Today I saw a 3" 37 with box and docs, 'bout the same condition as yours with a $500.00 price tag on it. That was in affluent Williamson County, TN. The gun shop will probably get their price.
It's a nice "J" frame and immenietly suitable for all-day carry. The provenance of being gifted to you by your uncle, along with packaging and documentation, makes it a priceless family heirloom, in my book.
Were it mine, I wouldn't fret over the cylinder turn line, they all get them and if you were to reblue it, it would return.
