Clock Gledhill-Brooks Time Recorder

[Mike Thatcher]

Hi, all. I have a Gledhill-Brooks Time Recoreder s/n 54484 (circa 1938-9), and in the storage process, lost the key. It appears that it is a "skeleton Key". There are alot of keys available on ebay, it would be helpful if I knew what I was looking for. Could anyone provide a picture of the original key so that I can look for a replacement? Or better yet, have a key for sale!
Thanks for the help, Mike.
