Vintage Dugan Winter Cabbage White Opalescent Crimped Rim Glass Tri Footed Bowl

Vintage Dugan Winter Cabbage White Opalescent Crimped Rim Glass Tri Footed Bowl. Width 6-3/4" Height 4-1/4" Bowl looks to be in very good condition, but upon closer inspection there are a few lines that can bee seen on the bowl and feet. I don't know it these are cracks or manufacturing imperfections as I'm not an expert in glass. Please refer to the multiple detailed photos for accurate condition and additional information.
