New pics in the Bolt Bucket link to the new US Radiator I got. I put the original 1950 3100 radiator beside it so you can compare for yourself.

Its the second choice below in my signature.. More Pics in the Bolt Bucket. Seemingly lots happening here, but mostly lots of sanding as usual!

The new one is far better spec wise.. here are the specs:

They say they use newer technology and fit smaller copper tubing in to increase efficiency. I needed it to handle AC someday.
