According to Eric Cherneff's excellent site: the Vigot-Bilstein jack and the Hazet 772 lug wrench included in the '53 toolkit.Frank Hood wrote:Which jack is correct for my car that was built in November of 53?

Re: Which jack is correct?
Both Eric and Spencer are right, however finer details do exist. The earliest Hazet 772/2 wrenches with an underline "L" were most likely in use through about 52-53 and adding GERMANY and using a straight line from about 53-56. "Angem" or to pend was dropped when the patent was granted in June of 1954 but existing stock meant that the “Angem” logo was most likely used until about 1956. So early 53 tool kits would not have "GERMANY" in the logo, later 53 tool kits would have added the "GERMANY" because of the change in the patent status. More data points are needed and both wrenches are hard to find... Good luck!
For Vigot jack variations see http://forum.porsche356registry.org/vie ... 13&t=39330
There is also a great deal information in the patent issued July 8 1949
A few notes on German patents:
Notice that for the Hazet 772/2 evolution the D.P. angem, then the locality of Germany is added then D.B.P, whereas the Messko gauge goes from “Ballon” to D.B-pat. U. GM.
D. P. angem is Deutsche patent pending or a local German patent pending; this is the first step in the process. Germany D. P. angem implies a German patent is pending similar to a federal patent pending from a local patent. This would be the second step in the process. D.B.P. is Deutsche Bundes patent, or a German Federal Patent. This completes the process and affords 20 years of protection. D.B.-Pat. U. GM, or 'Deutsches Bundes und Gebrauchsmuster is a legally registered federal patent giving ten years protection. The D. B. designation was uniquely issued after October of 1952; therefore, both the Hazet 772 wrench and the Messko tire gauge with such markings were likely later than October of 1952. The D.B. designation could have been used as early as 1949 for items patented in 1949 and later, for items patented up to 1949 the old designation of D.R.P could have been used until October of 1952. Of distinction is the designation of Und Gebrauchsmuster; this implies the difference between protections of the process and methods and the final product or item being protected. U. GM means that the Messko tire pressure gauges were protected as the product for ten years whereas the Hazet 772 wrench further protected the process and method of the wrench such as the handle that spins for 20 years.

Rick,
Here's a data point 772/2 from 51015, Aug. 10, 1953.

Re: Which jack is correct?
Thanks David! I think the change from the Hazet 772/2 with "GERMANY" probably occurred either very late in 53 or very early in 54...
Note that the image in the VIGOT patent is consistent with the image provided by Tom Scott showing the 1950 Jack in the link above. Tom is very likely right!
One other interesting aside is the repair of the Vigot jacks and the disassembly procedure but that is already covered in another post thanks to Brad Ripley!

Thank you Frank for being patient with the extended details.... Hopefully you have as much information as you need...
I have posted the untranslated addendum to the Vigot jack patent... if some one could offer better translations I would grateful...
