Note 2:  "L" underline with kickup to the left

the "L" wrenches were used up to about 1956

the "L" underline of the 10/14 wasn't as defined as the other wrenches.

Note 3: finish

-Had a Nickel Finish. Nickel will have a yellowish tint when viewed in natural sunlight against a white piece of paper. Wrenches used in the Porsche tool kits were nickel finished mostly during the pre A era.


-chrome plated finishes started showing up in 356 tool kits around 1955-56.


Note 4: number size and type

-Large font numbers are generally associated with early production mostly likely pre 55

-the numbers were also more "rounded"

-Earliest of 10/14 wrenches had a "closed" 4 as can be seen in this photo:

Note: This did not come with the kits, but is a nice addition to any tool kit. It is actually a pin.
