The team at White Mill in Sandwich, Kent, have come across a grinding plate mill spindle and are keen to offer it to a good home. It has no base or any other parts, but may be suitable for restoration.
If you are interested please can you send me an email (friends@millsarchive.org) and I will put you in touch with those involved.
White Mill is also a Mills Archive Heritage Partner and you can read more about the mill here.
