I.D. Help

[Hrodebert S]

Hello all, I am a seasoned user but new to collecting.
I have a unmarked pan that I can't seem to find in any of the I.D. links on the site.
It is fairly light, and cooks really well.
I am hoping some of the experts here can tell me what it might be.
Thanks for the time and knowledge.

my first reaction when seeing that hammered finish was going to be CHF (Chicago Hardware and Foundry)... they are kind of known for their hammered pieces... but after seeing the handle I'm not so sure. I don't think I've ever seen that style of 'small rib' handle on a CHF pan before. Usually they are smooth underneath the handle.
