Defendi Modamatic Garter carriage probably came with Defendi knitting machines, which are rebranded clones of Brother knitting machines. The carriage color scheme matches that of Defendi knitting machines.

Some sources indicate that the model number might be KM-3000.

I am still trying to figure out what Brother garter carriage this model duplicates. Some features hint that it is equivalent of KG88 or KG89 models. The give away is the absence of the wiggly lines on the button showing the direction. If the carraige comes with rails, then it is KG88. If not; then KG89.

I recently discovered a video showing Defendi Modamatic 3000 working on the machine with already pre-built garter rails. Thus, Defendi Modamatic 3000 is equivalent to Brother KG89 garter carriage.
