I was intrigued by your earlier post on the 44K1WH you have your eye on. Since this thread was started on High Altitude tractors, I was going to start a new thread on the 44 Wide Axle/Riceland tractors. But, since Tom already replied here, I will as well.
I have sitting in my barn 44K1WH 46904. It was converted to LP somewhere in it's life, but I plan to put it back to K. As Tom stated, there aren't many of these wide axle/Riceland 44's know to still exist. Until your post, I had the only K known of these. Now we know of two of them!
I had an opportunity on a 44D1WH a couple of years ago, but hesitated too long on the price. I now really regret that. I don't have any idea where it went.
Here's a not very good photo of my 44K1WH showing the LP conversion.
