Dear David.
First generation FLT132 which was made 8-10 years ago had the aluminum lens cell. If you use the telescope in cold weather minus 10C aluminum will shrink and add some pressure on lens cell as a result the lens will get pinched and you have to loose collimation screws.

Dear David.
So how the customer was using the scope without rings and plate?
That means no one was using the scope for many years.
This is your risk purchasing used scope, if the telescope is in perfect condition without defects that's ok, but if it was dropped, damaged, never used I would like to let you know since you are not the original owner and I am guessing that is first generation FLT132 which was made over 10 years ago, in case of any lens defects the lens can't be repaired because new lens design is different now.

Dear David.
From the focuser i can tell this is first generation FLT132, made around 10 years ago.
First we made in 2006.
If the place you live the temperature goes below 0, we strongly recommend to use dewshield heater.
Also, you slightly can loose collimation screws, in case the aluminum shrink in cold weather, it wont add pressure on lens elements.
