Authentic or Junk

[Jeff from Las Vegas]

Hello.  Not a sword guy.  Family legend is that this was given to my grandmother as a gift from a serviceman she was dating who had served in the south pacific before or during WWII.   We thought it was lost to the ages, as most family members thought it was junk.  It looks like pictures I see for a Kyū guntō.  But I don't see any kind of serial number.

Appears to me to be a genuine Type 19.

 

Any more photos of the handguard?

Yep, looks like a type 19 dress sword with mon (family crest) on the handle back strap. Appears to be authentic. Looks like the mon is that of the Matsuura clan. Someone might correct me on that.

Here you go.  I assume this is the hand-guard.
