Antique Reed & Barton Mystery Knife

Reed & Barton Victorian Era Mystery Pattern 

I'm looking for help identifying this Reed & Barton pattern. 
It looks Victorian to me and I have tried the following sources without any luck. 

Reed & Barton

Replacements.com

Silverpattern.com

I did find some info on Reed & Barton purchasing blank stock from Rogers Bros so I researched their patterns as well. 
Still no luck.
It almost looks hand chased, it's so gorgeous~

Thanks in advance if you can identify this pattern!
