OK BIG DISCLAIMER! NONE of these buildings are mine nor did I build them. Over the years on various auction sites, I created a file of unique custom built buildings, many with korber kits as a base. So here are some of those custom structures in my files:
Ace Tank Mfg.
Whitehead Petrochemical Corp. [Red Building looks korber-like]
Korber Water Tower on factory roof above
Coca Cola Bottling Corp.
REA Transfer Station
Korber flat
Korber Flat #2
Korber Flat #3
