Trev,
I bow to your selection of Peter and Ann Bateman as the maker of our spoon and think you are completely correct in this. I've included three small photos with this communication which I think prove your analysis as to the Batemans being the maker.
From the outset of attempting to make this identification, I have focused upon that tapering "tail" at the margin of the remaining hallmark on our spoon, all that time thinking that it must be the point of something like a shield into which was set the internal hallmark. Therefore I had looked at the perimeter of each hallmark for something that would fit that presumption. I now see that was wrong.
Since my last post I found another picture of the Bateman's hallmark and in looking at it, using your analysis that it was "sideways on", I at first could not make it match up as I was assuming that the "B" that remains on our spoon was the lower of the two B's (Ann's) that make up the hallmark. But then it occurred to me that it might in fact be the upper B (Peter's) of the hallmark that now remains on the spoon. And when I looked at it in that manner I got a perfect match to what I can see remaining on our spoon. My tapering "tail" is actually pointing into the top of Ann's "B".
Further, the "ghost" that I mentioned as seeing in the photo (the one that is currently "linked" to my first posting) I now see as being the latent "P" of Peter's first initial, along with what may have been an ampersand in their hallmark. That latent image can be seen as a "ghost" in the photo that is copper in color and appears to me to be almost birdlike. It matches what I see in the Bateman's actual hallmark. The three small attached photos are intended to give a visual reference to what I've just described.
Tom, I thank you for your very helpful comments and am grateful to you both for sharing your expertise with me.
My mother was a prolific collector of old english silver a half century ago and often took me along as a small boy as she toured antique shops looking for the next piece. I remember the very large hallmark book in our home during those years. Over half a century later I'm discovering that this is very heady stuff. It would be fascinating if this spoon could speak of what it has seen these past 200 years.
