History Irving (Arctic) Winter Shutters for Model B

Hey,

i'm looking for some informations and pics about Irving Fronts. Found some pics for Model T and A, but nothing for Model B.
I saw one as an piece, how to install them in the shell? Behind the insert, instead of the insert?

Thanks a lot
Frank

 

All I'm familiar with are the Pines Winterfronts for the Deuce. HRP

 

The Automatic was thermostatically controlled and the Arctic was manually controlled from a dash mounted control cable. Here's the Patent info

 

The patent page lists Irving as the inventor and Pines Winterfront as original assignee.

 

This is an Irving Arctic - but its different to the pic above or winters?
Isn't for a Ford i guess?

Thanks
Frank
