Help with maker into please

[antiqueknifedude]

I pick up an old German folding bowie knife with a maker that I can't find any info on, has anyone seen this one before? All help appreciated.

I checked online and nothing. It does have made in Germany and solingen stamped into it as well. Here is another picture.
