Joe, thanks again for locating that original keystone spring and round body spring guide for me a few years ago. I had a Sept 1940 rifle for quite a long time but was missing the original keystone spring, which can take years to find. Joe had a friend that was selling an original keystone spring with round body guide and I was able to buy it through Joe. Photos of the rifle, bore is quite nice too.
