Can't figure out what this machine is
Hello, I need help and I hope you all can help me. I am looking at this treadle machine. The machine has the word LOTUS where the Singer usually is. There is no badge on the machine but in the place where the badge usually is is the word Singer and in a half circle on top of that is the word Vertrieb. I've figured out that that is german. The machine is up for grabs a couple hours away from me. I'd love to go get it but am concerned about the parts issue. Before I drive there I love to find out all I can about the machine. They have no manual and one of the plates is missing. I'm attaching the phots that I have in hopes that someone can help me out. Thanks in advance.
