... what makes it "typical low domed Arculus"?
A simple, and rather blunt, answer would be, "Because Alan says so!"

But it would be fair to say that Alan has done a fair bit of research into Old English weights, especially Aculus. There is good evidence, through several sources, and with enough examples, to show that certain items can now be be reasonably attributed to Arculus (although Walsh-Walsh may still be another option in many cases). For this weight, I would say that several points, when taken together, indicate a "typical low domed Arculus weight":
- The style of the low dome
- The way the canes are set (a bit wobbly in all rows)
- The use of differing canes in the rows whilst still retaining a general match in the colour scheme
- The way the canes are drawn underneath the base but do not meet at the centre
But perhaps Alan can be more specific?
