The High Intensity Neutrino Source (HINS) project represents the current effort at Fermi National Accelerator Laboratory to produce an 8-GeV proton linac based on about 400 independently phased superconducting resonators. Eighteen β = 0.21 single spoke resonators, operating at 325 MHz, comprise the first stage of the linac cold section. We present the production status of the first two of these resonators along with progress on the slow tuning prototyping. In particular, we report on the
