Whale oil lamp, free-blown font, pressed lion base

My best lamp is 8 1/2" and in excellent condition. It has a free blown font with a pressed square scrolled base with paw feet and lions heads between the scrolls (see blue arrow in picture). The lions seem more canine with a mane to me. See Barlow & Kaiser # 2028 for the base and # 2029 for the font. There is smoothed chip on one foot. Sandwich, Ca 1827/35.
