Early glass fluid lamps are well beyond the scope of my expertise. The upper brass collar looks to be later electric conversion. The photos are probably the best description. Condition : Base has a shallow flake (see close-up, photo #10); otherwise Excellent with bold, vibrant color and tremendous detail throughout. The upper brass collar is tarnished and could use a general cleaning.
See photos for complete details and close-ups. Please consider them as part of the description. Measures 11-1/2H x 5-1/4W x 5-1/4D overall. Good Luck, thanks for watching, and be sure to bookmark my Auctions, listed and ending daily.
