Thread: Need "Expert" opinion1727 C Christoffersen G Felix Solingen

I recently was given a razor still in original box by a friend. I assumed it would be easy to investigate like everything else seems to be in the google era. On the box it says Gustav Felix solingen and what looks like gustav wedge?
It seems to be in good repair folds still sharp and no rust. The box also is pretty great
It has been extremely difficult to find any info on c christoffersen or the MN location
If anyone out there can give me some history and clue to its value I would appreciate it

On the blade It says

1727 girard ave north
minneapolis mn
made in germany
also christoffersen wedge on opposite side
