Was a breeze to use!
I really liked that the receiver has a plastic tube to hold the white wires. That makes it easy to replace the cord, because I remember changing those out on 1960's 500 sets.
Brand new heavy duty round coiled handset cords in black. These were made specifically for G1 handsets and the 500 and 2500 series telephone.
Four color coded conductors RED, Black, White, White to match Western Electric company 500 series telephones. Will work well also on ITT and Stromberg Carlson 500 telephones and G1 handsets. These also can be used in payphones where there is a G type handset.
