I am really late to this party, but I just ran across this post when I was trying to find more information about circa 1980s Jet brand anvils. Living in West Central Florida, there’s not a large selection of used anvils around and “real“ American-made anvils, when they are available, are fairly expensive. (I’m not blacksmithing or metal working, I just wanted one behind my garage to use occasionally when I need to pound on something!). So recently, I saw a Facebook marketplace ad for a Jet 50 kg anvil for $150 (6.5 miles from my house), and I thought I better scoop it up while I had the opportunity. I used it the same day I got it and it functioned fine for what I was doing. I initially had it on concrete blocks, but I just moved it to a Cypress stump yesterday (another Facebook marketplace, ad, free Cypress that was knocked down in the hurricane a year ago). I was hoping that in terms of quality it was a midpoint between Chinese ASOs and good American/European vintage anvils, but that may be overly optimistic.
