Wondering if anybody can speculate from afar  in this inquiry...

Our conservation studio is currently  treating a small private 
collection of costume objects and accessories; a few of which we are 
looking to identify more accurately.  The objects have some authentic 
provenance, in that, they are known to have been in the Chrystie  
family possession in New York City for the past 150+ years ( circa 
1840's).  The family has direct descendants from high ranking military 
officers in  France during the Napoleonic era in the early 19th 
century.  My vague recollection of this period is that Napoleon's army 
had invaded and was occupying Spain by around 1813 or 1815; and that 
eventually the British arrived via Portugal to force the French 
withdrawal.   Any information to further identify  these objects and 
proper nomenclature would be greatly appreciated, as well as, any 
references for publications on French Military Costume of this period.

Please see the images below.  The under-side label denotes a shop 
address in Lisbon, and the original box has a hand written label in 
French that is not clearly legible, the accompanying silk vest is in 
impeccable condition.

Thanks, best regards,
Elise
