For your consideration:
This is an early type of stethoscope from the 1890s called a phonendoscope.
The tubing is quite stiff and it looks like all the pieces are present.
Size of the case is 5 inches by 4 inches by 2 inches. (12.5 x 9 x 4 cm)
Case is labled M. RUPALLEY & Co. 27 Rue De Liege PARIS
Case is in good condition, the latch works.
I am certain with a more newer flexible tube, it should work just fine.
