I do not know how to identify my clock. I bought it for my wife on our fifth anniversary in 1980. It was running fine until 1983 when a "friend" thought he would "help" start it by giving the bob a good three winds first then letting it go. That fixed it alright! I stopped needing to wind it or set the time anymore. But it still told the time correctly twice a day. I had a clock repair shop fix it then and it ran fine for years. About 11 years ago I took it apart and cleaned and oiled it. I had it running well but we had to move within a year. It was packed for a little over a year before we had a place to set it up. It ran for another 4 years the and then got packed up again and moved. Four years later brings us to now and it does not run and it is time to get it running. I would like to identify the correct specs for the suspension wire and teach myself / learn the correct configuration for it to run. I am running into new terms I have not heard before like "flutter" so I think I have a bunch to learn over my 8-day clocks.
