Description: 1 5/8” diaphragm type scope. The diaphragm has a second attachment with a 1 3/4” long rod ending in a gutta percha cover, which can be used to localize sound. The tubes are rubber replacements and connect to ebony ear pieces. The small size suggests that it might have been modified for pediatric use.
