Conley's SBT book is the only reason besides the picture of Flues premises Buffalo from Robt. that I knew that Flues had done anything but design the eponymous Ithaca model. I have both 4E SBT w/ 5E wood and 4E double with swamped rib and I agree that the overall package--checkering, wonderful chisel work on the action--holds up well in comparison to the later NIDs.
