Yes these are made by KW and are very popular over here in the UK. The brand is separated into three companies with quality varying slightly between them all as you might expect due to the price difference.
KW - Top of the line, stainless steel, plastic spring perches (corrosion resistant),
best quality internal components, twin tube, most comfortable ride,
Weitec - Mid range, galvanised steel, plastic spring perches (corrosion resistant),
internals reported to be near as good as KW but not confirmed if they are actually the same,
twin tube, ride quality comparable to KW,
AP - Base range, zinc plated, anodised metal spring perch, lowest grade internal components,
harder springs, reported to have the harshest ride quality,
