Ok guys,so what is the final conclusion on the Sheerline? Another fact that may support the the current model 6 as correct may be the use of the edger slot...maybee he wanted to give it one more go? Or maybee the sheerline was designed during the run of the model 5 when the groove cover was still a possibilty. It was very common for manufactureres to design years before release,this is very true for cars.

My point is the groove cover was deleted on the model 5 leaving the next model blank. So would it not stand to reason this being the same for the sheerline? Im still of the opinion that the way we know them is the way they are meant to be,especially when the "Sure start" Impulse was a later more modern starter than the Recoil. Anyways just food for thought.

The main reason Im commenting is my sheerline has the edger base but earlier tank on cowl style with the sure start" I was also of the understanding that they came without the edger slot? BUT Ive seen in this post reference to another member having both styles,AND the man I bought it from had it since new...So How to Proceed? I have all of the information you all have but still,to many discrepencies.

I want this sheerline to be accurate....All opinions and assumptions will be appreciated.

Also my engine number appears to be that of a model 6,not 9 was this old fella a little senile and it had its base changed at some point? lols. Do I need to just find a NON edger groove base,just to be sure. I thought I had the sheerline info pretty much under control,but little things keep coming up to alter general concensus...I just want this Resto 100% accurate. So simply...DID the sheerline we know as 9,come with either base style?
