Ebay is one option, but expect lots of tyre kickers, and people to turn up with little idea on how to move the machines.

Ebay is good to get an idea on values, if you search completed listings.

Other options are the home workshop classifieds ( https://homeworkshop.org.uk/ ), or Model Engineer classifieds ( https://www.model-engineer.co.uk/classifieds/ )
Just make sure you get get some good photos, and highlight that it will be up to buyers to move the machines.

Then there is the other option of selling to a dealer, who will likely offer you next to nothing for everything, but they will remove it all.

I've personally got no idea on values, but the Bantam looks to be a fairly modern one.
