Rear mudguard identification

[Garry Easter]

Hi,

We are trying to identify this mudguard; Comes from us clearing a workshop, container and small barn from the late Denny Barber, so we would like it to go to a good home too (once we can list it with a tad of info!). Hope the photo attachments are okay and thanks in advance for shedding any light to the clueless! This is the last of our 3 posts, so fingers crossed!

Thanks,
Garry & Kate
