Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts. In years half of the C in a sample will decay see figure below. the problem is this long number is the serial number and we need the machine model number to help with parts feet needles etc. The Singer k was named the Rolls Royce of sewing machines because it was super smooth in operation thanks to the full rotary hook and precisely made carbon steel gears. But the K was manufactured years later at around

The Singer K was manufactured over many years from then reproduced again in called the Singer N. The calibrated date is our best estimate of the samples actual age but we need to be able to return to old dates and recalibrate them because new research is continually used to update the calibration curve. A huge amount of work is currently underway to extend and improve the calibration curve. The light aluminium frame was only wide even with the fabric rest down it still was only. Im sure its still the smallest adult sewing machine ever produced. In the early years of radiocarbon dating a products decay was measured but this required huge samples. Radiocarbon dates are presented in two ways because of this complication. But C is not just used in dating. The second difficulty arises from the extremely low abundance of C. temperature and chemical. Tree rings can be counted and their radiocarbon content measured
However hopefully this page will help identify your sewing machine model number in conjunction with the other details we have available relating to sewing machine serial numbers.

Despite Three cbs dating show the differing body shapes and apart from its smoothness the K can be recognised by the large disc with the stitch length lever protruding from it. If of the carbon in a year old sample is from a modern contaminant the sample will be dated to around years. Its manufacturing year was to The Singer K as shown has the sleeve arm or sometimes called tubular bed. The K has a bed size of so is much wider than the KEvery plant and animal in this chain including us will therefore have the same amount of C compared to C as the atmosphere the C C ratio
