Our old cutlery is apparently Dubarry pattern (fairly similar to that linked below) which looks to be a very similar profile but less fancy than your Kings pattern. I much prefer using it over our newer Newton, see my other post in this thread for what I think about that one.

Off down the rabbit hole, https://www.antiquesilverspoons.co.uk/knowledge-center/all-a... seems to be more about the decorative pattern than the basic shape and balance.
