Yep, he copped some well-deserved flak there.
From the ODK 'Victa Model 4 Automatic Specifications' thread
HERE, it looks like the green text version corresponded to the Concord factory address [1955-58].

The Victa factory moved to Milperra some time in 1958, and it looks like the text colour changed at that time.
THIS past thread has a reasonable pic of an original tank decal with the Milperra address.
Of the Victa 18's with cowl mounted tanks, Models 3, 4 and 5 may all have been made at both locations, as far as can be determined by the Victa Green Book. A lot of the 18's about have been 'bitserised' over the years.
