Isle of Wight Pottery with mystery seahorse mark

Just picked this up today as assumed was I O W. Half of the mark is missing but then I noticed the seahorse could anyone throw any light on this for me please. Thank you.

Ive not seen a seahorse mark but I think it has Jo for Jo Lester in the black stamp

Thank you the design matches with other Jo Lester items I’ve googled, but I haven’t come across a pot like this before. It’s quite crude and not very well fitting I wondered if maybe not many produced because of this. Any thoughts. The seahorse mark is a bonus and very much like the design on the plates he’s made.

It became a bit of a franchise with other potters being allowed to use his mark , hence the variable quality

I don't recall ever seeing this seahorse mark on any of my own pieces,
neither can I find any reference to it in the IOW pottery book.

How odd ok at least there’s a reference to it now. Having a run of the unusual this week.👍🏻

Do you think the mark would increase the desirability (if that’s a word) to a collector?

Only if they recognise it. Otherwise as desirable are the rest of Jo Lester’s IoW Pottery atm
