THE CALM ONE!!!!
Yah that's a block off plate which is a really good thing to have. Looks like you've got male end down piping which is good too. I'm not sure why that giant hose clamp is on the slip section? To try and hold it from moving I'm guessing?
Exterior masonry chimneys are giant heat sinks and a lot of heat is lost to th outdoors unfortunately. Masonry has little to no 'r' value. You could look at the top of the chimney from outside and see if there's just a clay tile poking out or if there's a stainless toplate/cap it probably has a full liner. A full insulated liner is what I would recommend in that situation. An exterior masonry chimney requires 1inch of clearance from combustibles all the way up from typically the top of the smoke chamber. But if the liner is insulated with 1/2 insulation that would bump it up to ZC to combustibles. That's code for the USA too.
