Sorry can't help, am also a proud member of the "not past 43" club...
In fact just finished one of my shortest ones as my sub was lost with all hands on Jan 25 1940 (in real life yesterday, which comes handy as I had to install anyway the last 2.4 NYGM version) After a convoy attack, got too impatient to come back and finish a large merchant, was spotted by escorts, had to dive deep to escape and forgot my hull had been earlier damaged by airplanes... crushed at 140 m...
So it's back to Sept 39 with the new version installed.
