These are recolors of the internet-anonymous 1965-1967 Volkswagen Typ.1 Beetle into four Philippine Police liveries.

Nothing else in the file changed, other than the credits.

Just realized that after comparing with another VW recolor project that these are actually 1:68, not 1:72. Will fix that when I get the chance.

Edit: 17 December 2018
Files re-scaled to correct 1:72, contents changed and split over 2 files that replace original. Second file's recolors based on VW Beetle from
