I agree with Roy. It's a flower on filigree cushion, not a crown (although the cushion does follow the same form as a Crown weight, especially those that have the Crown flattened rather than rising to the top of the dome).
In Colin Mahoney's book on Paul Ysart weights, he described this design as being a "Flower with Radial Ground".
The Harland weights with an H cane were intended for the UK market. I do not know how many of this design were made but I think that most had a PY cane and were shipped to the US. I have seen very few of the H cane versions.
I do not have an example of this design (or a Crown, for that matter) so I, too, could generate a bit of jealousy on a bad day.
