And my 2nd Luft has this TM also.
You can notice that characters in "Solingen" are taller on JohnZ's logo.
And the word "Fridericus" is different also.
I examined Whittmann's Luft book, and found a 1st Luft on page 68 with the same logo what JohnZ has on his dagger, so that's why I think that is the early version.
