356, 356A:
Made by Continental, had a white (possibly orange as well?) label with Porsche and Continental marked on it.	White label Is this label a different color, or has it changed from aging? Another variety	Codes: EU, BO, RN, FB, HR. Can anyone decode these?
Late 356A? Another type of Continental, but marked with Porsche like the Phoenix variety. Marked with "Prestretched" on the opposite side from the label I speculate this dates from the late 1950's. Please let me know if you have more information.
356B/C:
Made by Phoenix, various versions of the label with Porsche and Phoenix marked on it. The label also includes what appears to be a date stamp, in a Y/MM or MM/Y format, where the year was the last digit of the year. Earlier ones did not have the "/" between the month and year.

Hammer (Pre-A)
300 gram wood handled hammer for who knows what purpose! It would probably do more damage than it helped...

Appear to have come from several suppliers, including Jorg (left) and Peddinghaus (right).

Decals:
Jorg - appears to be the same as that applied to the screwdrivers. Note the example is the less common 2 color version.
Peddinghaus - decal states:

"bürgt für Güte
und
1a Ausführung
jedes Stück
geprüft"

Thanks to Rick Albro for taking the initiative to figure out what this means, and to Alexandra Susan Keriakedes for the translation as follows: "The performance assures each piece is examined for A1 quality". Knowing this, it would appear that the decal is a quality control sticker.

The hammer below is a currently available Peddinghaus hammer, with the handle reshaped more like an early version, and a repro decal applied.

Hubcap puller (late T6B, 1963, maybe 1962)
Looks like a small screwdriver (total length about 145mm) with a blond handle, and a 90 degree bend approximately 1 cm from the end, finished with a point. used to remove hubcaps by way of the small holes on the perimeter of the cap.

Reproduction warning: Stoddard sold repros that were distinguished by having two flat surfaces on opposite sides of the handles, rather than flutes.

Sunroof screwdriver
Used on electric sunroofs in the event of motor malfunction, dead battery, etc. Stamped "Golde".
