I just got this. Can anyone help?

I just picked up this bike. I believe it's a rollfast, but I'm not sure. It has a working New Departure Model DD 2-speed, a fur covered seat, and a spring loaded 6-hole rack. I'm not sure what year it is, but I am excited about the 2-speed.
Any help would be great.
Thanks
Johnny

Here are the picks of the Rollfast.

Here we go. I've included a pic of the rack and of the sprocket. Any help would be greatly appreciated.
Thanks

Rollfast

It is pre WWII, it has the frame tabs for a rear kickstand.
