Hi Bernie,
To add to Tom's and Ed's replies; it may be difficult to know exactly which Erfurt inspector was assigned to a fraktur letter stamp and for how long. Not sure if such Erfurt factory records survived over the years.
Here is a link to some Fraktur characters, for your info :

Based on your photos, the thickness of the metal of your two tools, and the aging apparent on both of your tools...I, too, think yours are authentic...IMHO.
