Does anyone have any information, or know where I could find information on an import/export business - I believe they dealt in crystal of some form. Have no idea the name of the business, but it was run by 2 brothers - Kenneth and Laurence Gyger. They closed shop around 1960, retired and both moved with their wives to Sun City, AZ.
I'm just trying to fill in some blanks - Kenneth was my grandfather, although I never met the man.

Thanks for any and all help.

After a little prodding elsewhere, I found what I was looking for. The company was the National Crystal Company and was in business from approx 1934 to 1960.

Thanks to all that gave this query a look and anyone who may have thought they knew.
