Hello Garth !
Congratulations for the new book ! I will be eagerly looking for the appearance of it. Your PT-Boats in action is one my best favourites from Squadron Publishing. I especially hope that you will include foreign use of World War I subchasers and their precise role in the end of U-Boat offensive.
Geez, ITC/Glencoe had a terrific 1/74 World War I 110' Subchaser. It's no longer in production and I could not locate one anywhere, including evil-bay, to buy.
Don't surrender the ship !
