Cased Remington New Model percussion pocket revolver, cal 31

Cased Remington New Model percussion pocket revolver, cal 31. The wooden case is of the period and especially made for this revolver, containing the correct bulletmold and powderflask.  Key is not present. 
The revolver is serial 8752, has a 3 1/2 inch barrel with sharp adress, works fine, third variation having the rion triggerguard.  Orig. rosewood grips are excellent,  metal has approx 95 % , what seems to me, an dold reblue, works perfect.   Hard to find small Remington, This was the last of the percussions and most were converted to rimfires.
