Two-valve Ricord speculum built in steel and with ebony handles and signed by Bordeaux [in Paris]. The instrument can be dated around 1850. Note: a little play in the curved ruler which allows you to adjust the spacing of the valves and the thread is worn, otherwise good original condition. The instrument measures 23cm in length
