Like Macybaby says, your Honeymoon is made by Davis and uses a Singer 1x2 needle which translates to Boye 10 or an industrial MTx190 can be substituted. The serial number is located on the front bobbin sliding plate. Butler Bros., a large mail order house similar to Sears, was one supplier of these machines and shipped by rail across the country. Davis went bankrupt in 1924 and your Honeymoon has a 1910's look to it.
