This is most odd. To replace the spring would have required removing the rear bolster and center back pins as well. The rear bolster is finished cleanly and the center back pin has been spun, so it is really weird that the pivot pin looks like that. Also, it would have been peened proud and filed smooth. I just do not understand how replacing a spring leaves you with a pivot pin BELOW the bolster surface. And the surface of the pin is rough, not at all what it would look like if it had been finished properly and then pulled in, say by using the blade as a pry bar. Its weird. Does the blade wobble?
