No, I haven't. The razor actually came with a small card that stated "Compliments of Lt. Comdr. J. J. Tunney". J. J. Tunney was better known as Gene Tunney, who in his day was famous world champion boxer in the 20s and defeated Jack Dempsey twice. From what I read online, he went onto work for Schick in the 30s before being recalled to military service at the outbreak of WWII where he served as a Lt. Comdr. in the USN. This razor dates to about 1941 so it could very well indeed have been a gift from the famous boxer.
