That Wigit chassis and speaker are going to be tough to find, but you never know what might turn up.  To make your quest slightly easier that same cabinet was used for two different models:  the model 47 was the 4 tube Elf and the model 48 was the 5 tube Wigit:

As you can see the speakers are a reed type with no real frame so they are pretty fragile.  I haven't pulled the speaker in my Wigit yet, but the cone was damaged when a snake (a pet of the previous owner) crawled inside the cabinet
