Leather Military Flap Holster for Colt Model 1851 Navy Percussion Revolver

With “L C” stamping on inside of flap (possibly Lower Canada?).
This holster is in overall good condition with scattered losses to outside layer of leather but overall sturdy. The flap securing strap is attached on the back and comes forward to close on the brass retaining piece in the English style of the period (further leading one to the Lower Canada interpretation of the above noted cataloger’s opinion).
