Coleman enamel and unknown glass shade

Good Day

My recent finds include these items. I would appreciate item identification and general information please.

I beleive the Coleman shade could be similar to the one fitted on the 242B on Terry Marsh's site, but cannot be certain.
I have set the unknown opalglass next to a Tilley 182 onion for size perspective.

 

The large white glass shade fits a veritas gas light.

Just a guess, but the shade may be from a table lamp - no slots for the bail arm to pass through

 

The shade will not need bail cutouts for lanterns where the bail fits into the burner castings as the shade will be below the bail.

 

@Andrew T doh, most of my lamps are Tilley so the bail fits to the frame
