The lion rampant and date letter(?) bear a passing resemblance to a Glasgow 1853 hallmark but without the duty mark and town mark:
Leaving aside the unlikelihood of a partial hallmark being passed I note that the lion rampant is not correct (note the height of the tail for example) so I don't think that this is a Glasgow mark. It may be the picture but there is a dullness in the metal which makes me suspect that it could be pewter rather than silver. If it is, in fact, silver then I wonder about an Indian or Chinese origin.
