Here is the mark of distributor Carl Henkel, Bielefeld. Henkel ran a Fire Department equipment store that started in 1871 & exists to this day.

You can still find the occasional Henkel marked blade on Eban or dealers' sites. This long model with magnetic pommel came with an unmarked frog that I'll compare in a subsequent post.
