Hi Geof
The sump plug on my Sigma is a shouldered bolt but doesn't have a separate washer.
I've seen some Fiesta plugs on the internet which are M14 x 35mm long though not sure if this is the correct one. I think the best thing for me to do is to drain the oil which will give me the chance to identify & get a new sump plug if need be whilst the car isn't being used.
Thanks for the photos though as It shows that there are differences.
