Ginger, can you look at that serial number again. It should start with a letter. The serial number you are giving is for an 1873 machine. That is a Model 66 Redeye, which they didn't start making until 1902. Being that it is electric, it is either a 1920's 1930's model or it was originally a treadle that had a motor added later? Again, the first digit of your serial number should be a letter. The bobbin slide plate is easy to find. You can do a search for a Singer Model 66 or a Singer Model 99 bobbin slide plate. They both work on that machine. Billy who runs this board also sells the slide plates.
