These complete flipper assemblies appear to have been made in Italy. They are new in the box. Several European companies like Zaccaria and Playmatic made machines copying Gottlieb so these mechs will be compatible with your Gottlieb machine that uses this style of flipper assembly. It will work for older EM Electro mechanical machines, Gottlieb system 80 and Gottlieb system 1 machines as well.

You might have to change the coil for the proper coil strength (see your manual) and change the flipper bats to the longer style if your machine has longer flipper bats. These ones come with 2 inch flipper bats but you can change to the standard 3" flipper bats no problem. 

See pics and let me know if you have any questions.
