The Rustler:
Denbys @ Lincoln used to do flat trls to Europe - though not sure if they still do.
Also Smiths @ Scotter do lots of “flat work” though not sure if they do France … worth a call, as may be able to help.
Denby still do, i see them quite a bit with john deere stuff on at the ports. Pretty sure thats all out of JD’s place nears karlsruhe.
