[CR]What kind of freewheel is this?

There is a 1940's Legnano for sale on eBay with Cambio-Corsa:

Once you have the auction page opened, please scroll down to the fourth photo.

Wondering if anyone out there knows what kind of freewheel this is and where it was made. Hard to see what it says on the freewheel because the drop out "arms" and Cambio QR rod are in the way.

I emailed the seller regarding my question, but in the mean time would like to try to find out sooner; that's why I'm asking the list.

I have a freewheel exactly like this one only it is a five speed as opposed to the four speed in the auction. On one half of the cover on my freewheel reads: "BREV CAIMI "(followed by a clockwise arrow); the other half reads: "G. CAIMI-CASTANO-ITALY".

Any help with this would be greatly appreciated.

Thanks,
