Anybody have any idea where the traditional old "red phone" can be purchased? If you're not familiar with it - I mean the old style phone with no buttons or numbers, just a phone and a red light. It's connected to another one and when you pick one up, the light lights up on the other. They're often connected with either regular phone cord or sometimes a single XLR cable. Any info would be great! Any substitutes of equal simplicity would be great too. Conditions are - it must be silent (or with a snip of a wire, capable of being silent) and minimal amounts of cords used to operate it. Thanks- J.
