As newbie of this outstanding forum I am very impressed of this extrable knife thread.
Thank you for sharing your great information, Wetzel 206 09, and for showing your collection's knives.

I like to show a couple of nearly identical extractable German knives, being marked by different German cutlers from Solingen:

The top one with bottom bolsters is a Hugo Koeller, the other an Ed. Wuesthof TRIDENT one.

Hugo Koeller's c.1970s sales catalog is illustrating the knife:

I could not research any details on the nearly identical Ed. Wuesthof knife without bottom bolsters, anyway Ed. Wuesthof's 1922 sales catalog is illustrating onother different classic pattern:

BTW: I learned that the colloquial German term ‚Saufaenger‘ for this kind of knife obviously is being translated by collectors in English as ‚pig sticker'.
