Dean, you asked: So, other than being a early model ss dagger there would be no criteria for trying to increase likelihood that it was presented at the FHH ceremony based on maker or any other factor?

There was nothing to suggest that it HAD to be an early dagger. There are RZM daggers dated 1934, 1935, 1936, etc. It could well have been one of those. Depending on how long the ceremony lasted, later ones could all or mostly RZM daggers.

Unless there was a dedication added afterwards, I can't see how one could be certain that any particular dagger could be identified as being presented at the FHH.
