Thanks for the information. I did see that one website that mentions a Marguerite, it basically was just a blog of someone that found one but really no other info. The gentleman that has it is second generation sewing machine repair/sales and has been doing it himself since the late 40's if I remember correctly. He is a wealth of information but said he has never heard of a Marguerite before.
The one patent date I could read looked like 1874. The decal is in amazing shape for being over 100 years old.
