Here is some info on NFI:
After WW2, under allied (US) control, DAG was renamed NÜRNBERG - FÜRTHER INDUSTRIEWERK, NüRNBERG (NFI = NÜRNBERG, Fürth Industrial Plant) which produced ammunition from 1948-52.
Initially they reloaded existing cases and marked the hs with dual “o o” 's. Examples:
RWS o 6.5X57 o (M17)
RWS o 8x57JS o (M32)
RWS o 8x57JR o (M2)
RWS o 8x57JRS o (M33)
Even other manufacturers cases were used: eg “FN o 7x57 o” (M46)
It has been rumoured that the "double o’s " were produced by FN for NFI but this may be speculation because “FN” hs were often used but the same technique was also shown on RWS cases…
Later, as RWS were not allowed to use the “RWS” trademark, once again an ‘N’ hs was used during NFI period (1948-52). In these cases the existing hs was milled off (incl examples of the ‘RWS’ and “29 39 40 BS” (M2) ) and a “N” hs used (see “N 8x57J”, “N 8x57JS” and “N 8x57JR” hs).
NFI packets are also known containing steel case cartridges
eg "RWS * 7x57 * "
The 1953 RWS catalog had a small appendix on NFI showing that they still producing adding machines with the “NFI” label at that time.
Thanks for sharing the box info Dutch - I will add your info to my database.
