This Bakelite 3-Prong Terminal Receptacle is all original and includes the three post thumb nuts for the backside. These are often cracked or chipped as Featherweight machines were placed in their cases when the terminal would get caught on the right side of the case, causing it to break.
The round pin receptacle will fit US and Canadian Featherweights with the plug that has the cords exiting on the top.
If you need the flat prong terminal (which will fit the 221Ks and 222k Featherweights that have the plug with the cords exiting on each side), then they are available by clicking here.
* Bakelite Plug is not included.
