It could be that my anvils were simply custom forged with some features left in and some left out. Now I see in the catalog that HB took custom orders. I had the clip horn but no swell, because perhaps the swell had not been thought of yet. Its a great anvil and I personally really like the horns on these guys. Hay only did these stampings on their 2 piece anvils. For instance, my little anvil had one pritchel hole because perhaps someone on the staff had not yet thought of two pritchel holes.

I often wonder whether the differences were because the company was transitioning from blacksmiths' to farriers' anvils, and it was making changes little by little. It had the clip horn, no swell and only one pritchel hole. Again, many years later, a 140 pound HB farriers' anvil came to me. It has a narrow face, a clip horn, and two pritchel holes. It is very sleek looking, one yard long and one foot tall. It's a great anvil and I personally really like the horns on these guys. It weighed 213 pounds and had a good 5'D swell to the horn.

Another HB farriers' pattern came to me many years later. It had two pritchel holes but no swell to the horn. I was traveling with a farrier, and it turned out to be a farriers' pattern with the clip horn. I got my first anvil, a Hay-Budden, from a San Pedro, CA, ship salvage yard in 1963.
