I found three hole shares!! Osmundson makes them (Thanks, grandpajohn!). I don't know how long it would take to get them factory direct, but they had them (Osmundson #) at the Depot. They were put on the truck an hour ago & will be here late tomorrow morning, early afternoon. I also found landsides & heels. Didn't even know my plow had heels. It does explain why the landsides that are on there have extra holes in them.
Oh well! I've learned one thing out of all this & that is, if you want to feel like a kid again, buy a well worn machine you know nothing about & have no manual for. I think I need more practice in the sandbox. ;v)
P.S. I always wanted to get into blacksmithing, but I'd have to trade one hobby for another. Otherwise, repairing shares certainly sounds right up my alley. I have worked hot iron a few times, the last time was when I needed to cobble up a new trip rod & other pieces for the bundle carrier on my binder. They ain't pretty, but they're the right length & havent bent or broke yet.
Also.... The share on the second bottom had a bump left where a snout may have been, before I started plowing. So, I think they started life as a deep suck share.
