Vintage/Antique Crystal Frosted Eagle w/ Unknown Maker Marking

Stunning Frosted Crystal Eagle in Near Perfect Condition! No damage, chips, cracks or breaks. Some micro scratching on base seen with magnifier. The eagle has a marking under the tail but I can not make out what it is. I do not know the maker/brand. Upon research it could be Vintage Cristal D'Arques or Antique Lalique Crystal. Measurements: 7.75in Height 6.5in Wing Span 4.75in Base Diameter 4.8in Width From Tail to Head
