Excellent condition. Estimate its early 1900.s. I am not certain but the metal appears to be copper. Measures 12 1/2 inches tall. Base is 5 inches across. From front to back measures 7 inches. This is a wall mount. Inside is really clean as shown. The oil resivoir is completely glass as shown from bottom view. See close ups. No damage - perfect condition. Excellent collector piece for any vintage collector or farm house decor. I see these selling for over $100.
