I've put the circular unidentified plaque (below left) next to a 'Southwick' Wesley (below right) for comparison. The text on the unidentified plaque is finer, with long elegant serifs. There is a space after the 'M' in Methodist on the unidentified plaque, and a slight space after the 'o', so it reads:
'M etho dist'.
Whereas the spacing on the 'Southwick' plaque is as follows:
'Meth o dist'.
For interest, Keith Lovell has provided an image of a second similar bowl.
