Re: Film of Erie Type 8 resistor manufacture
Tricky nailing the date of that production- never before have so few obvious clues been given- not even the captions give the slightest hint.
The box for my hi-stab (1W) Eries is a different style, with red print on the label but still very low grade cardboard. As NOS items they have kept very well- Seven 680k's (1% tol) are only high by a mean value of 0.6% and a maximum of 1.3%. Four of the seven are within 0.4%.
