TJR Trading has dated this piece to the 1850s.
It is monogrammed 'CR' to the cartouche at the front. The rest of the silver plated section is machine turned.

Unfortunately the lid is stuck fast so the hip flask cannot currently be opened. Some of the silver plating is wearing off and it shows signs of wear. The glass doesn't appear to be cracked or chopped at all.
