Dear Forum:
I have a question regarding an AA4100 Candlestick with "RD1974" on the ID decal showing the set name, trademark, etc.... I need some help with , please.
I know the "RD1974" may refer to Northern Electric/Northern Telecom telephone companies, but for some reason I can't find literature on the AA4100 Series that had the Customer ID (telco.'s) it was made for, and am racking my mind trying to remember that ...
Also, I would appreciate if a Forum Member who might have documentation on the AA4100 could lookup the model code breakdown information for that series Candlestick, please.
Thank you,
