Famos 120 Burner Variants
It is known that tooling for Famos lamps was acquired by Veritas from Ehrich and Graetz sometime in the 1930s, but it is not known if this was just for fonts, or if they acquired the tooling for burners as well. However, Famos burners must have been made in England during World War 2 and post-war whilst German industry was in chaos. These burners have slight differences from earlier ones, so it is possible that Veritas made their own burner tooling.
Because parts are almost totally interchangeable between Famos 120cp lamps, it is almost impossible to give a definitive pronouncement on date and country of origin. The first Famos lamp I ever bought (I now know) had a foreign-made font, a British-made Superspeed burner, and a British-made non-Superspeed gallery.
However, if a number of samples all have the same parts, it is reasonable to assume that they are “kosher” and have not been swapped around.

British or Foreign?
No Famos burners carry a model number, country of origin, or other way to positively identify the date or place of manufacture. However, there are two distinct styles of 120 cp burner, apart from the Superspeed and later developments. It is not known for sure if these simply represent changes made to reduce cost and to improve the burner, or if they represent a a change from foreign-made burners to British-made ones. Certainly, Veritas must have been making burners in England during and after WW2, when German industry was in chaos, but it is not known for certain when they started, nor if the tooling was shipped from Germany or if they made their own. If a number of German-made lamps were found in Germany with burners of the later style, this would indicate definitely that Ehrich and Graetz had already switched to this design and then sent tooling to England. On the other hand, if only lamps with the earlier style of burner are found in Germany, it is still possible that Ehrich and Graetz shipped new tooling to England but continued with the old tooling in Germany, much in the same way (but the other way round) that Aladdin shipped old Model A tooling to England and changed to the Model B in the USA.
Some lamps can be positively identified as British-made by the style of the font and the wick knob. So far, I have not found any that can only be identified by the later style of burner, but as we cannot know for certain that all later style burners are British-made, I shall refer to burners as as “early” and “late” rather than “foreign” and “British”.
The differences I have observed between early and late burners are as follows:
1. At the bottom of the burner where the basket narrows in two steps down to the screw thread, early burners have a radiused bend, whereas later burners have a sharp corner.
