Hi.
Thank you for taking the time.
You have basically confirmed what I had found out.

I was aware the the U-40 was sunk early in the war and probably still carried both her deck gun & net cutter.

I was hoping someone would have come across a definite date for when these items were removed from the U-37 - but as indicated in your research it seems like no-one knows.

I also concur that the camo scheme depicted on the Mirage\WCM kit is from her Atlantic patrols. Perhaps I will build her with this camo and deck gun, but no net-cutter.

Thanks again.
