Pre-Worboy Road Signs

Can anybody contribute a pre-Worboy 'Ford' road sign?
The two signs pictured are from the small village of Tregidden in Cornwall found either side of the pretty ford there. On first appearance they look like pre-Worboy signs of yesteryear but on closer inspection are probably not official signage at all. If anybody knows of an authentic pre-Worboy 'ford' sign I'd love to hear about it.

Here are two linlks to one found in Gloucestershire by David Howard:
Pre- Worboy Ford Sign - front
Pre- Worboy Ford Sign - back
