Model 1877 Waltham

Have acquired this movement. There is no identification other than serial number 1111933 and KEYSTONE on the back plate. Can find no reference to a Keystone 18 size KW movement by Waltham. Any info appreciated.

Hi o. c. kid,
In the Pocket Watches, Beginning to End book there is a listing for;

"Keystone - 18s - 11j - HG77L - U - "PSB", (EA 24)"

which would make it a P. S. Bartlett grade.
