Here are two more fancy bolster Verlangerungsmessers. The 1st pictured is only marked "PATENT 19946" on the blade. The bolsters do not have the fine grooves as shown on the others. This knife has no button or visible lock and comes apart at the plain bolster side. It sold on Ebay for $747.79 with 13 bids on Mar. 6, 2022, even though there was no sheath and the blade had rust marks and the tip was damaged. The 2nd pictured Verlangerungsmesser is marked "Louis Hanau, Coln" and has a monogram on the less fancy bolster side. Note that "Coln" is the old German spelling of Cologne. This picture was from Mr. Kaeshammer of Germany who believes this example is from the mid to late 19th century.
