Ok, I was getting ready to type a really long e-mail and about crowns etc but then I looked at the pictures again and I think I picked something up. There is a photograph of the tashes at the back of the doublet and if you look really carefully at the stitching - it is terrible. Certainly not the sort of tailoring you would expect from a military tailor. Further, the tashes on the front left of the doublet look crooked. I don't think this jacket had tashes, but at some point, for whatever reason, they were added.

Perhaps it truly is a franken-doublet.
