The festschrift for Barclay Head is in the public domain and fully (beautifully) digitized! What a fabulous portrait. We should all do so well as to appear so dapper for history.
This provides us with an image of RRC 2/1 that’s wholly in the public domain:
Both Crawford’s image (see last post for link) and this one are taken from casts. I’m not sure they are the same cast. Regardless the plate itself is a nice sharp image one can zoom in on. Click on the photo for the link.
I note that Gàbrici gives the weight as 10.15, whereas Crawford as 6.14g.
