Antique sewing machine, unknown maker
Hi! I bought this sewing machine today at an antiques shop. I'm unsure who manufactured it or when it was made as the only indication is the initials G.N. I found similar machines made by Grimme Natalis & Co but not this exact one. There is a serial number of 232897. Can anybody help me to identify the age/manufacturer of this machine? Thank you!
