Re: Iver Johnson Hammerless
Welcome to TFF.
Those patent dates were marked on the butt 1907-1911, but an R serial prefix indicates a large frame black powder .38 S&W caliber second model made 1907-08.
However, check the number again, as the book indicates serials did not exceed 100,000.
The serial no. should also appear without the R on the trigger guard and under the top strap when cylinder removed.
Value would probably fall in the $50 to $150 range, depending on condition.
