NOTE: Tom Felt 2025:"I'm pretty certain that these are Gillinder. I noticed the lack of serration, but suspect that may be due to mould wear. Not a 100% guarantee, but I don't know of any other company that made a similar shape." Known in crystal and opaque turquoise, Nile green, and custard, made in 3 sizes (7-8-9H, bases 3-1/2"D, 3-3/4"D, 4"D). Largest size has gold -encrusted decoration at base. ref Felt-Stoer, The Glass Candlestick Book vol 2, pp86-87 and Tom Felt, Museum of American Glass
