I can't find anything stating that permission must be obtained for using black and white plates. Where have you seen that? I can only see that the vehicle must be pre-1980 and in the Historic Taxation class.

A bit more detail on their website, but not much: Fiat Pavesi P4/100 Artillery Tractor of c.1920s SO390 - Berrybrook Steam & Classics

Also worth trying the South Yorkshire Transport Museum. I think Peak1 might be involved with them. South Yorkshire Transport Museum | Facebook

Have you seen this thread? Looks like it was owned by a member called Peak1 from Sheffield back then. Don't know if they are still active on here though?

Probably not military, but this picture has been posted on the local Then and Now Facebook page. Can anyone identify the 1921 truck? https://www.facebook.com/groups/bristolthenandnow/permalink/1421639378041427/

Their Facebook page says "Due to COVID the Heartland Museum will be closed until 11/12/2020. Sadly, the Veterans' Day Parade will be canceled this year. Stay safe!" https://www.facebook.com/heartlandmuseum/

Looks like it might be the The National Automobile Museum in Reno. This link says "After the HATM closed, a portion of the collection was donated to our Museum and is currently stored in a local warehouse." https://automuseum.org/?event=a-video-tour-of-the-hays-antique-truck-collection-august-second-thursday-talk Even if they didn't get the Riker, they might know where it went.

Think it's one of these. Also known as a Bog Frog:

Yep, think you're right. http://www.bmpt.org.uk/other_boats_history/RSL-1664/index.htm

This site will be useful for research. http://www.bmpt.org.uk/index.htm Difficult to tell what it might be from the photos.

Googling the reg number, the roadsweeper was sold at auction. Can't see the sale date though but possibly 2015: http://classiccars.brightwells.com/viewdetails.php?id=5461 Found a picture of it from 2018 here: There is a chocolate express bus in the London Transport museum collection - not sure if it's the same one though?: https://www.ianvisits.co.uk/blog/2017/11/05/see-the-pirate-chocolate-express-bus/

Yep, Scootopia.

They have a website too: https://www.joesmotorpool.com/

How strange!! Could you make up a puller to remove the bushes using the internal thread?
