Made this XL file up a few years back. Things have probably changed since I left CT.
Few changes since you created your file, but you are spot on with the majority. Nicely done!
Mashantucket (Foxwoods) no longer uses "Station 59" as no one else around us utilizes the station number concept. We are now just saying "Mashantucket" followed by the unit designation & number when we go mutual aid. Our apparatus are simply Engine 1, Engine 1, Engine 3, Tower 1, HazMat1, Squad 1, Service 1, 2 3 & 4 on our system. The chiefs are using F-1 for the C-O-D and F-10 for our deputy chief, adopting the old bingo numbers.
New London are also using the simple Engine 1 style radio designations. Not sure if they are still using the "A" unit designations for mutual aid.
Ledyard, Preston & Montville never adopted the eastern station number, they are still using "R", "P" and "M" respectively before their apparatus numbers.
Norwich does not use the "N" designation anymore, nor have they used it in a long time.
HOWEVER, the Sub Base FD now is using "N-6x" (for Navy) before thier apparatus numbers. This was done when they did the base fire department re-alignment a couple years ago, NL Sub Base is Department 6 on the US DOD (14C) system.
