Marshalltown G71752 Transformer Thermometer This item was purchased from an inventory surplus sale. We do not know the history of it. The box is in bad shape, but this unit is in very good cosmetic condition. It looks like this is possibly an assembly that was kept as a spare or was refurbished and ready to be put into service. The box that it came in was marked, "Koppers WA 47386-36, 4/0, T-2E, 25W, 30/250 FTC, 36" but the box was in bad condition and was discarded. We are not able to test it. It only comes with what is shown in the pictures. S211-16 D12-1 d 81019178 rl fdk 80313228 80815228
