Letter Opener of Nude Female possibly laying on a rug. It is a yellowish color metal with a very strong odor..possibly pot metal,brass or silver? Not sure if antique look is actual tarnish or was applied to make it look old. Two small spots on theopener have tarnished a light green color...possibly indicative of metal type? The female is approx 4 inches tall together with the scroll & opener/blade the piece is 9 and a half inches long. It si heavy for a letter opener My son thought this could possibley be a hand dagger as it did at one time appear to have a serrated blade that is now dulled.The only makers mark I can find is a triangle(underneath the scroll) with a line straight down the middle. I have researched but have not been able to identify the mark. I do not know the provence. Thank you. Sincerely,Kat H
