that is a 3 bottom model BER plow for eagle hitch tractors. EX14 denotes that it is the later "throw away" shares and moldboards as opposed to the older CX "blacksmith" bottoms. The rear moldboard will need replaced but EX parts are still available. 16" and 14" parts will interchange so dont worry if you can only find 16" parts.
Your plow has the optional hydraulic depth adjust mast and the optional gauge wheel.
It is a nice plow with alot of potential and I would keep it if I was you. Try to track down the coulters if possible. Do not put on a non-breakaway plow coulter on the front bottom. If your plow does trip and the mast separates it will strike a non-break away coulter and most likely break it or the clamp holding it to your plow.
