Help Id Mark On Serving Spoon & Fork - Lion Rampant, Shield

[kardinal]

Trying to get any info on the pieces. If no-one can recognize the mark at least can you suggest country of origin, age, etc... I have doubts that they are sterling but any good way to test them without using acid?
thanks in advance!

At least, do you think they are new or old? What does the style and the pattern suggest? Thanks
