Thanks all for the info and comments. I have spent more time on the forum reviewing what has been discussed concerning Hay-Budden anvils.
My sister and I purchased one from a blacksmith at Saratoga Race track,Saratoga, NY for our Dad's 50 birthday. He had a number of jeweler and salesmen's anvils but no full size anvil. I live on the Eastern Shore of Maryland and seem to run into blacksmiths that know about them, but do not own one.
Thanks for the information about the company it's building and location in Brooklyn. Both Hay and Budden had porte cocheres on their houses where their carriage driver would pick them up out of the weather under cover.I have pictures of my Great Grand fathers house which I will post in the future. His house was large Victorian with a wrap around porch, we lived next door at 109-07 86th ave, Richmond Hill, NY. Thanks for your input, Richard Budden
