Smith & Wesson did not make the Double-Nine. High Standard did, and it was available with two cylinders. One was a .22LR cylinder the other was chambered in .22 Magnum. sales@countrygunsmith.net
Must be inspected by a good gunsmith.
$325 in excellent down to $55 in poor condition. Add $45 if you have both cylinders and $20 more if it is nickel plated instead of blued.
the R-107 was made for .22 LR only I believe. the R-106 had dual cylinders for it. I would contact High Standard and find out. But from what I know, High Standard R-107 didn't come with a Magnum Cylinder.
One website says the High Standard Double Nine W-100 series was manufactured in 1958, the first year of that model.
