Unusual 18th century spoon

[amena]

I have a spoon constructed in a somewhat unusual way.
Around the bowl, on the back, there is a raised edge.

The only image of a spoon constructed in this way , concerns a Maltese coffee spoon of the late 17th century.

The marks on my are very worn, and the only one who I can recognize it's the mark of Bologna (chalice) that came into use in about 1745.
Does anybody have other examples of spoons made in this way?

Hi Amena
In France this spoon would have what is called a bord bouche, found on both large and small eighteenth century spoons as a reinforcement on the outside of the bowl. This technique is considered a sign of quality. Although found all over France, spoons like this were particularly prevalent in Alsace, and often found on pierced spoons.

The larger spoon is unmarked but probably dates from circa 1730. Spoons in a similar pattern have been noted bearing the mark of Paul de Lamerie. That does not have to mean the this spoon comes from him, but it is a heavy, well made spoon. The smaller spoon is by Lothian and Robertson, Edinburgh, 1761. It copies the pattern but is not as substantial a spoon.

This is a rare pattern in Britain but it shows that we sometimes made spoons with a moulding round the edge of the bowl.

Thanks to both for the contribution.
It seems to me that in the spoons submitted by agphile the edge is more like an embellishment, while in the spoons of which I have posted photos, as I understand, it looks like a construction system.
I hope that someone else will post more photos and information because I think the topic is interesting (at least to me)
