<- Note:

The Transition from "L" underline to "straight" underline is blurred. As well as from Darker Plating to Lighter plating from Pre-A to Late Pre-A to Early A. Then, there is a change-over in the size of the "Hazet" logo from 20mm to 15mm in length. Generally, it is accepted that the 15mm Logo and Silver Finish would be found in "Early A" kits. But, older tools could be found in newer kits. However, newer tools would not be found in earlier kits.

The Hazet Schmalkalden plant was destroyed in WW2 (between 1939-1945)

Based on catalog logos:

 

"U" underline appears prior to 1938:

 

"L" underline appears in 1949:

 

"straight" underline appears in 1951 (although, back cover had "L" underline:
