Victorian maker's mark


I need some help to identify this maker’s mark.
Any ideas?


WH is William Hunter. No doubt you have identified the hallmark as London 1842/43.


Thanks Phil!

Have you seen this kind of “w” before? It almost looks like a “triple v”.

I have to confess that I didn’t notice the strange W. I suspect it may be some sort of double strike. But it does look like a very neat job.
