Note: difference between Mk I & Mk II (noticeable differences) – the nose on the Mk II is more slanted where the gunnel meets the deck – the Mk I has a sharper rise. Only the Mk I had the original GILFLITE stickers. The engine box is also different as well as the dash. This is all according to David anyway, I have asked him to specifically write this down. However, he prefers to make these spec lectures when I am in the middle of something else. Oh and the Mk II is clearly longer as well. Hopefully more info on it’s way !!
