C-Map cartridges for Autohelm plotter

[Tom.]

I have an ancient but still working ST50 Autohelm plotter. Am looking for Cartridge charts that cover French Atlantic coast. Does anyone have these?
Don't have to be up to date as this is only used as backup resource.

It uses CF85 cartridges, which were discontinued many years ago. You might find someone with a cartridge lying around. Worth keeping an eye on eBay.
