Mouse over the photo images to zoom in. I do not know the full-scale current ratings. The meters are identical and could be used in a power supply or amp. Part numbers are as follows: 27447 and 49, OC/A085-21.
They measure 4.94K and 4.95K ohms on the DMM. Both meters are in good working condition. Offered is a nice pair of SIMPSON Panel Type Voltmeters. Each is clean and in good condition.
Each is a 5-volt type. Each deflects when DMM measured.
