Another thing, if you want to replace the tube shield bases see if you can get some from a 1937 model as that will accommodate using types other then "G" style tubes in the future. The 1938 bases were cut up because they don't allow anything other then a "G" type tube to fit into the socket, so I suspect a lot of these were hacked up during the war years, or post war, or during Korea when there were tube shortages. I think the original rivets were more like copper or brass eyelets, and those are easier to put in.
