Default Re: AVO Multimeter survey

Yes 17754-74 would be July 1934; on examples from the 1930's the decade is assumed, thus my early smooth side DC Avominor 1034-93 originates from Sept. 1933.

The figures for production between Sept. 1933 and Sept. 1936 are surprising- around 40,000 units. This was a popular device! From Sept. 1936 to June 1941 another 22,000 were produced.

In the 1930's (certainly on full size avometers anyway) sometimes the serial number and date codes are reversed, which can cause confusion.
