An original flute from the Paris workshop of Louis Lot, first part of 20th century.
 
Soldered tone-holes, C foot,  keywork showing no wear to the hinge-tubes or pad-cups.  The silver-plated tube measures .014 inches.  The flute  was constructed with inline G, and soldered tone-holes.  
Traditional  scale, sounding length is 600  mm (A = 440).  I see no sign that the head has been cut shorter or altered in any way.
 
The flute has not been "re-tuned".
Embouchure measures 10.1 X 11.8 mm.    Embouchure plate is solid silver (sterling), the tube is silver plated.
 
The instrument is listed in Lot's record book, the entry dated May 27, 1926.  Owner of the instrument was M. F. Moreau, resident of Vesoul (Hte. Saone).  "Remise a neuf"  means  a full overhaul.
 
The flute is part of a small collection of French instruments that I've acquired  over the years, which means I may offer to sell a few more in the upcoming months.
