Anyone have any info regarding the individual on this personalized Heer dagger (early Wingen)?

Back of crossguard inscribed:

Leutnant d.R.
Dr. Münzel
Panzerregiment 1
Erfurt

If he was a Reserve Lieutenant early enough to be in Panzer Regiment 1 (1935?) he may have achieved a pretty high rank by the end of the war. Actually, I am trying to tie together the individual on this dagger and a General Oskar Munzel who survived the war and subsequently served in the Bundeswehr.

Thanks for any assistance.
