I am trying to restore my wife's grandmother's Ami Rowe Jan Diplomat to working order. I have everything else back to working order with the exception of the latch coil. I am having a hard time locating a replacement. There are no markings on the coil so I am not sure what I should be looking for exactly with regards to one that would work since I cannot locate one from a parts machine. I am located in Ohio, USA. Thanks for any help....Ben
