BADGER Crescendo 175 & 175T

Hi,

I recently purchesed a Badger Crescendo 175T . While surffing in the web , I noticed that the airbrush  is also sold as 175 without the T letter . Mine has the T letter engraved on the body.

Is anybody knows if there are differences between 175T and 175 models ??

Thanks
