I was looking at this touring today, not the best pictures, it was owned by a mourner from a church, the top removes very easy, note the back where it comes down square not an angle so the people had privacy, also rear window rolls up, Bob
Has anyone ever seen a top like this one,Bob
There were a lot of various after-market tops made in the '10s and '20s. I have heard them called "mourner" or Mourning" tops a few times when the back is closed off that way. But they are also known by more cheerful names like "California Tops". From what I can see in your photos, it looks like it may be a well made top and may be a very interesting car to tour with.
(More photos would be nice hint hint.)
Drive carefully, and enjoy the holidays! W2
