Unknown hand grenade

[Amunicionador]

Hello everyone!
Can someone help me identify this hand grenade?
I can not find data in any manual.

Looks like a Ketchum (US Civil War era). Is there a hole in both ends?

Do you have some dimensions ?
The bullet is not a great help !
No screw into the fuze hole ?

Hello!!
-No hole in the end.
-Broken thread in the mouth for the fuze.
I'm at work now. Tonight I will send measures.
I bought it at a flea market years ago. The seller only knew that it was from WWI.
I bought at the same time a Austro-Hungarian ball Rohr hand grenade like this http://thebignote.com/2018/01/11/au...reat-war-part-two-the-ball-rohr-hand-grenade/
that it has cost me a lot to identify. The seller thought it was a deutsche smoke grenade!!!!!
