As least on this subject - you are way off. I was a mechanic for a large Wisconsin engine dealer not long after the Stellite valves and seats became an option for repairing older engines, and standard equipment on all new Wisconsin engines with a "D" at the end. "D" stands for Stellite exhaust valves - and NEVER indicated "distributor" as you state. Many older Wisconsin engines, built before the D-series -were available with magneto, battery-distributor, generator with a piggy-back distributor, etc. A.F. Milbrath was the chief engineer and vice-president of Wisconsin Motor Company around the time they started using Stellite. I still have copies of the company's press-release and explanation of the new D-series - along with some articles written by Milbrath on the subject.
Also - just about all the older Wisconsin repair and parts manuals explain this - telling the owner what the "D" means. Look at any of the TE, TF, VE, VF, books, etc. The VH engine was a newer design and, as I recall, by the time it came out Stellite came standard. So, I don't think there ever was a VH4 - just a VH4D. The older engines came both ways - e.g. TE or TED, TF or TFD, VE or VED, AEN, or AEND, etc. &c.
"Models with a "D" at the end is the same as the basic model. It just means it has a stellite exhaust valve(s) and seat(s). Stellite exhaust valves and seats have a coating of cobalt material which is much more resistant to premature failure due to high combustion temperatures. You can tell which ones you have as stellite valves and seats are non-magnetic and the coating is applied to a stainless steel (non-magnetic) base material. "

Today's Featured Article - Using Your Tractor: Creating a Seed Bed - by Chris Pratt. When I bought my first old tractor, I had only one idea in mind. It wasn't the preservation of old iron since at that time, I was unaware that people even did this. It wasn't to show off my restoration skills (though I had tried my hand at a couple of old motorcycles in my teens and if I recall correctly, those old motorcycles were sold in boxes about one quarter finished). It wasn't to relive memories of Grampa, Dad or myself out on the back 40 nursing the Farmall pulling too many b
