Zsinj renamed the (fill in blank) to the Iron Fist!

I remember that Zsinj got a superstardestroyer and renamed it after his first ship, A victory class star destroyer named the Iron fist. My question is what was the SSD called before Zsinj renamed it?
Also when did this occur?

 

"Zsinj's flagship Super-class Star Destroyer, the Iron Fist was originally christened the Brawl."

From the Unofficial Encyclopedia.

Dunno when he took control of the SSD, though...

 

I always thought the Brawl was kind of a lame name.

BTW, I read this in an official source too, but I don't remember which.

 

Cracken's Threat Dossier

 

I think the Brawl was just a working title given to the Iron Fist during its construction by the Empire and KDY. I thought that Zsinj commandeered it from its construction dock @ the Kuat ship yards, renaming it after his first command.

I don't know why I think this, and I can't back it up....

... so basically I've got nothing...
