Glad to see some of those models we've been working for the past year getting a work out.
You must have converted them back to the old format for them to work in 1.2x, correct?
I took the opportunity to replace the very oldest models I never replaced when I did the 1.5 upgrade in 2006.
Used some of the models we produced working on the 1.6 version a few years back. Removed the 1.6 only additions and reverted them to AITW slots.
The Fokker DXXI is yours from 2014.
Moggy added very important french and german and british (the famous Defiant add-on !) aircraft which were missing. I have the 1.5 beta from Moggy long ago and it's a very good add-on.
I still need to work out how to work the Defiant switch under W10
