There are a lot of them around, setting in barn lots, etc, both IH and aftermarket in the 450 to $250 range. Most of the ones for an M will also work on an H by changing or turning over the front mounting brackets. The big thing to watch for is the cylinders being internally rusted to the point they cannot be economically repaired. I got into that on the loader for the H that members of the board restored for me. Even though the cylinder was closed, the inside was to the point it would have cost $700 to repair them.
