I have trolled these forums occassionally the past few years in the hopes of someday rebuilding my oliver. Got a bit excited when i saw this post, because it is the only other OC-3 I have seen with the holt blade. I am clearly lucky that my OC-3 remains completly unmolested after so many years. I was told by the local antique tractor expert that my blade was home made, he even claimed part of it was made from a piece of pipe, which i disputed. I am not even sure where I am going with this post, or why it would matter to anyone else, but here are a couple of photos of what should have been the original configuration.
