Frosty: Good to keep in mind.
George N. M.: Thanks for bringing to my attention that good ergonomics for a bad back is something to think about.
JHCC: Thank you
ThomasPowers: I finally got pictures of the base on the horn side and found some markings that are hard to read, I'm hoping once I clean it up it'll show up better. The underside is mostly solid with a small hollow under the waist. On the underside of the horn there is a hole on the waist that does not pass through, the heel side does not have a hole in the waist if that helps narrow down the manufacturer. The anvil is 100 pounds, I don't think it's been through a fire that I know of yet. A previous owner before the seller spray painted all over it for some reason.
From what I could read of the markings the first picture looks like: A 1 1 8 1 5 4
Second picture looks like: 7 5
The anvil measurements are 25" from horn to heel, 3.5" on width of the face. Height is 9", foot length is 9.5", foot width is 8"
