Dave,
The theory I addressed in my above post should have included the assertion that the signature was added as well, but I was concentrating on other points. For the record, I�m convinced that these daggers with signature are period. One of the daggers I�m aware of was first seen with signature and 800 silver chains in the state of Wisconsin in roughly 1965. The collector attempted to purchase it then but was unsuccessful. It wasn�t until the late 90s that this dagger was finally obtained.
