If they are the same man, then it doesn't matter whether the badge is on a chain or a ribbon. Also, the badge does show that the location of the original crowd photo is in the borough of Woolwich.
We have been using the list - but not all the mayors are pictured on the interwebs. My friend is going to the Town Hall later in the week, where they might have photos of them all. However, if both men are one and the same and we can date the picture (it's on the photo dating board), then we can identify him sooner.
He will also be visiting Greenwich Heritage Centre, too and will hopefully find the lorry hire place. I'm having a look online in the meantime. All help appreciated.
Thank you.
