This is my very first post, so if it belongs somewhere else please do let me know. Have been following watchuseek for years, picking up advice on various Ebay obsessions / junk for many years, so a very warm hello to you all.
I'm trying to find out what this movement is, currently inside an old JW Benson 1930s 'tank' watch. I assume it's not original as its not signed anywhere.
Any of you clever folks have any ideas?
Many thanks for any help!
