Hello and Welcome to Just Answer,
My name is***** am a Personal Property Appraiser and would be happy to assist you with your question.
These old singers are great pieces of sewing as well as domestic history. Your model 127 would've been produced in Elizabeth, New Jersey in 1892. In excellent working condition your antique sewing machine in the original oak cabinet with the cast iron base would have a retail antique shop value of 225-275USD.
Any mechanical damage or cosmetic damage to the decoration on the machine or to the cabinet itself would detract from the resale value.
I hope this information was helpful to you today.
Best of luck with your antique sewing machine.
Any feedback you can leave for my service would be much appreciated.
