On the right hand end is a bishop's mitre which, at first glance, looks like a crown. Next to it is a an animal that I assume is supposed to look like the Lion Passant denoting British sterling silver, but it's not. It's a ram, or a figure of Aries. Second in from the left is the outline of a man's head, again, supposed to look like the Duty Mark on British silver. Then there's the "maker's mark" on the far left, which appears to be "dd", but they're lower-case, when most British maker's hallmarks are upper-case only.
The marks appear on a meat dish ...



My assumption is that this is silver plate, with marks intended to look like British silver assay marks, but I can't find any other examples, or identify the true maker. Has anyone seen these before?
Many thanks for any advice.
