That`a a great early bottle, but how do you know it`s Connecticut and not another Hartford in another state? I`m only a couple towns away from Hartford, CT and in all my years of collecting I have never seen or heard of this bottle. I did a quick check on the internet and didn`t come upwith anything on this. If it is CT, then it`s quite a rare piece, and it does look like it could be an early Willington glass works piece, or even Glastenbury or Coventry glass, if it is from CT. No matter where it`s from, it`s a great bottle!
