I have 2 T/A 312 and 2 T/A-1 phones. The TA-1s do not require ANY batteries and are sound powered, with a range of about 4 miles. The TA-312 take 2 D cell Batteries but many people don’t realize that the TA312 can be used without batteries for a distance of around 4 miles. If you use the 2 d cells it can go about 12. Sportsman guide has been offering brand new rolls of field phone wire for $27 which is incredibly cheap. Over the years I have managed to scrounge up some spare parts (going through $1 boxes at gun shows pays off) and even found some of the “crystals” that are used in the non-powered manual switchboard. Allows you to connect multiple phone when you want to. You don’t need a switchboard you can wire them in a hot loop but all the phone will ring and everyone can hear the conversation, which isn’t always bad. If you get a roll of wire try to find the reel handle it makes deploying and retrieving the wire very easy.
