Lid is Marked Parkers #446. I am definitely no expert on antique coffee griders. I do not see any other markings so I am not even sure if the lid is orginal to it . It is dirty and will need a cleaning. I am not going to attempt taking it apart to clean it.  I will leave that to the purchaser. It has been mounted on a piece of wood. The wood is not original to it and has  split. I was going to remove it but feel it would had extra stability for shipping so I am leaving it on. The arm turns easily with no issues. I do not see any chips in any of the glass. It is in good condition especially since it is approximately 100 years old. Please message with any questions that you may have prior to bidding.

Will pack with the utmost care.
