Project "19"
After completion of the "Replace" project, LAAO (Lockheed Advisory Office) personnel in Nörvenich inspected all Lockheed aircrafts to determine the modification status. 
It turned out that there was still no uniform configuration "2056D" achieved. According to the latest Lockheed construction documents, which apparently only the LAAO submitted, 
up to 60 SB's (Service Bulletins) were missing on the individual aircraft. There is an LAAO report from 14.10.1962.
It was therefore decided that the affected 19 F-104G should be retrofitted again by staff of Heinkel from Speyer at Nörvenich. With the instruction of the BWB FS 173/51315 of 30.10.1962 this action was initiated. 
But for the reasons already mentioned, this work could not begin until January 1963.
The following aircrafts were re-modified again: factory numbers: 2043, 2044, 2046 - 2049, 2053 - 2058, 2060 - 2066.

8 aircrafts were changed to such an extent that they received a new tactical code:
2049 - DA+253 to DA+232
2057 - DA+122 to DA+112
2058 - DA+254 to DA+234
2060 - DA+257 to DA+237
2061 - DA+258 to DA+240
2062 - DA+129 to DA+119
2063 - Da+259 to DA+239
2066 - DA+126 to DA+120

10 of these aircrafts took part in the "Category III" tests: 2043, 2044, 2046, 2047, 2048, 2053, 2054, 2055, 2056, 2057. "Category III" were tests of operational mission profiles and system tests from April until July 1963.
