I bought a 1977 made 48-3 in the mid-1990s. I sent it to S&W in 1997 and they fitted it with a 22LR cylinder. I have a factory letter for the pistol and I also kept the paperwork for the cylinder work too.

It works quite well, but really, I rarely use the 22LR cylinder, since I have a Pre-17 and Pre-18 I can use instead. The 48 has the 8 3/8" barrel and shooting the 22LR out of that is kind of fun, but the 22WMR are more fun for me.

The pistols is in excellent shape but doesn't have a box or papers. I have no idea what it is worth today.
