Awesome!What is the number on the lower crank half Luvpsi?This will be the last piece of your puzzle for a close to exact model description as we can give:)I would at this point say its a model 4 still since the base and engine combined fall into the model 4 time line.The lower crank half single digit number would more than likely be a 4 or a 5?As for the green some would say it should be avocado,BUT its your mower and your preference,personally if im doing a rarer restoration of an accurate model then I will use Avocado,But different colours make for a change and also enhance the mowers appearance,As an example...Al(Alwil) has a vast colour array on a few of his specials and they all look Amazing go and have a look and see if they appeal.The choice is entirely up to you! and dont let anyone tell you how and what your resto should look like.Have fun and cant wait to see how you go:).
