Can You Identify TS or JS Mark? - possibly John Shelly / Jean Smith?

Hi, I have this glazed vase with the follow makers mark; though have had no luck finding out who they are.  Can anyone identify the mark which appears to be an S over perhaps another letter such as a T of J of something completely different? Thank you

Thanks Dantheman - here's some, more to its true colours as the other jpeg was altered to see the monogram easier.

Possibly John Shelly, Bath Pottery

It does seem to be John Shelly, which makes sense as it's been here in Bristol since at least the 1960's. Great find, and thank you NaomiM!!

Comparable mark, though monogram impressed rather than raised on Winchcombe influenced pots:
