This fantastic vintage red dial telephone is most likely from the late 1970s or early 80s, and has been tested and is working, it rings in and accepts calls, and will ring out. It does however have a crackling sound that can be heard, it sometimes goes away after a while but does need to be mentioned. A collector would know how to fix this as it is probably just a loose connection.
The red case is in good condition, it does have a light scratch to the edge near the number 1.
The model of the phone is Telecom 802 AWA 81 S.1/234
A great old vintage telephone for the collector.
Good luck with your bidding.
