The "B's" in Glastonbury Abbey look quite consistent, possibly suggesting an actual font?

Or an accomplished lettering artist, more likely...

Dave Smith, who I think is from neighbouring Devon, restores and reproduces a lot of this type of signage. His fonts for Letterhead are a similar flavour, but all look influenced by styles from slightly later than this.

Thanks Justin, you lead me onto John Studden's LHF King Edward which could make an interesting substitute for me.

Many Thanks
