2 Similar Early London Silver Spoons

Two very similar mid 18th century London silver serving spoons of heavy grade manufacture. Both are in very good condition. 
One has really clear hallmarks for LONDON 1763, made by John Swift.
The Second one the hallmark is a bit rubbed but it is of the same period. 

The John Swift spoon has a very nice pattern to the back of the bowl.
