Medieval Instrument Cases

[Matthew Allen Newsome]

Greetings all and sundry (yes, Sundry!  I see you lurking over there in 
the corner!).  I come to you this day with an inquery.
Now, I know of several excellent sources for medieval instruments, but 
what is out there telling us what medieval people carried their 
instruments in?  Surely they had some specialized cases to keep their 
instruments out of the elements and safe from jostling about while on the 
road.  Are their any good sources I could look for?  Does anyone know 
themselves?  I am a cordwainer, so leather cases would be convieneint for 
me to try and make, although my lady is handy with wooden constructions.  
Any help would be appreciated.
Aye,
Eogan
