If someone happened to save every piece of gas pump literature a question like this would be able to answer. Who knows what these pump companies did to sell their pump. There very well have been a "farm version."
Keep in mind, farmers didn't buy gas pumps. Most were given to them by the local gas distributer, with the understanding that they would buy their gas from them. These pumps were usually used pumps coming from large cities that changed pumps every 3-4 years. That is why you will find a Shell pump in a area that never had a Shell distributor, they never even bothered to change the signs on the pumps when they were put on the farms.
I would really look at the pump, try and determine if anything was removed, then decide should I return it to the original 10-H or leave it as it is.
