Large Veterinary Spring lancet
These are extremely large and very powerful veterinary spring lancets.  The item is armed by pulling the handles R to L (red arrow).  These units are unmarked.  A similar item is shown in Davis (pg 96 figure 103).  The item in the book is either from a different maker or is defective as all other known pieces have a secondary spring that returns the blade back into the case after firing.  The piece is likely German or Danish.  Other marks that have been seen on this form include: Tresch A Landshut, and KBLONER.
The screws on the back of the items make it possible to open the case and regulate the depth set mechanism.
Cases open to show the large blades and arming springs.

This piece is contained in a nice wooden case with 2 blades. The depth of the cut is controlled by advancing or withdrawing the sloted depth foot at the front of the piece.
