Crystal Decanter Help

[Indian Steve]

A good friend gave us a matching pair of decanters that had been in her family for a while. They 11 3/4 inches tall including the stopper, 9 1/8 inches tall without the stopper, 2 5/8 inches across the glass top, 3 1/2 inches across the base and weigh 3 pounds 8 ounces. The stopper is stamped Sterling 637 and the stopper on one is etched 62 and the glass decanter is etched 62. I guess the numbers were to match the stopper & glass. It has 8 panels. Does anyone on here know a possible maker or age? How do you remove the milky looking film inside? I also posted this in the "What is it" forum before i remembered the glass forum.Thanks

Steve... I did a quick few searches on some ideas on this I had for you and came up short.
But... I will give my guesses anyway...

Cut lead crystal decanters...1850's.

Hope this helps... Closest I found.
