No idea. But the Freud is sold by many retailers who get to specify
the quality of the case and the number of extra accessories you get
with it. This controls whether you get 3/8" or 1/4" collets, and if
the 1/4" is a collet or just an adapter for the 1/2". The model number
might just be this variation.
Buy a second collet nut from Freud (UK Freud is good at spares, and
reasonably priced). The collets are a pain to move between nuts, so
have a nut for each. Also ditch the 1/4" adapter and get a real
collet, if you don't already have one.
Another accessory well worth having is their turned brass guide bush
set. Beautifully made and quite cheap.
