RARE/VINTAGE AWS JAPANESE MADE "SPERRY INSTRUMENTS" Multimeter, Model SP-140.

RARE/VINTAGE AWS "SPERRY INSTRUMENTS" JAPANESE MADE, MULTIMETER. It's a model SP-140. It measures voltage and resistance, etc. See photos of the instrument close-up to see all of its functions. It's a model SP-140. It's a VOLT-OHM MULTIMETER TESTER. It is in its original American made leather, C7B, Metal closing clasp case, and includes the original wires and probes. It is in good working condition considering its age from mid-19th-century. The testing unit was made in Japan. I received it from the original owner, an older gentleman, who had no further use for it. Getting up in age, I have no use for it either.
