I called the number and left a message yesterday. A guy called me back (I was having reception issues but I think his name was Garret?). It is a google number which they are using for their apparently new business (the email he gave me is linked to a website domain which hasn't been built/published yet. They are planning notchback lense covers for the end of summer and it sounds like they have capability of doing custom lettering. If they keep their deliveries up, I'll be buying at least one set.
