For perspective of size,  cases  1 & 3 {internaly}  are the same height as a Brown Bess musket. {60 inches.} not sure about case 2.
Would like to have recorded more data than I did, other than photos, & sparse notes  & did with some kukri, but theres probably between 1000 & 1200 weapons on display. {manily kora, kukri, khanda, katar & tulwar.}
 I could have happily stuided each piece for several hours!  
 
If only!
