Hey man..
I have a Bon Bon spoon very similar to that one. I dont think that you have the HCU1 Pattern.. there are too many differences. In case these pics dont show up, I've also provided a link to another shot of the HHCurtis Pattern HCU1.....

also... check out the trademark and how its raised and not recessed. It took me almost 6 months of searching to find this info out.. as you can tell.. the trademark is very hard to make out. Also.. as you may know.. manufactures sometimes shared designs/ partial designs because of the artists involved in designing the pieces. But eitherwat... I would love to know who makes your piece because the tie marks on the cross hairs of the bowl are very unique to the spoon we have.. most others use a cross like pattern.... Anyway... hope this info helps... and I'll be on the lookout for your pattern and who makes it.
Sincerely...
Mike
