German fishing knife help please...

[skullmaster]

Have any of you guys ever seen a Fight'n Rooster knife based on the Muskrat design with one regular blade and the other a fish scaler? My Dad had one when I was young, I remember scaling bluegills with it. He lost it back in the 70's and has been looking for another one ever since. He said he thought it was a Hen and Rooster but I think it might have been a Fight'n Rooster model from what I remember. Has anyone ever seen this model in any German knife brand? I would like to get him a replacement for his birthday. We have both been looking at knife shows for years with no luck. Any help would be appreciated. Thank you.
