You mean was there a dressed down version of the Automatic deejay? I have always been of the opinion that this is correct. There are far to many mower examples with simply an auto badge fuel taps and/or groove cover nuts that are not nor have ever been True Automatics. This is still one for speculation as no Images or records exist.

We do know that the Model 4 Plain jane DID exist as its been seen in manual images.
Note the last image jonesy has put up for THE Special" You will note is is running the Model 4 Base....But what it doesnt show is either an auto badge or Special badge. So how it was marketed no one seems to know.

So The True Auto Finished and certainly a plain version model 4 or a model 4 special existed. The model 4 Non auto and Model 5 S1 special were so close in production that they all but ran into each other. We are talking now of only a few months if not less ..

So I guess until its proven we can only say for ceratin at this point that a Model 4 "Non Automatic" Existed between The Automatics end and the Model 5 S1 Began....Is it actually a special? As yet no one can confirm 100%. So If you have a model 4 with a special badge and it has a serial before approx 180,000 then chances are it is accurate as its run is so close to the model 5. the same would apply if you had a model 4 with and auto badge that also had a serial of up to 180,000 again because this is when the Model 5 S1 started so it would definately have been finished by then. We are talking about a mower amount of lets say betwee approx 128,000( Autos end) to 180,000 approx for (Model 5 S1 start). This makes around 50,000 mowers in between...So if they are making,as unkies ad suggests approx 3,000 mowers a week thats 12,000 a month so in four months we have our 50,000 mowers. Halve it for the STD and this may make around 25,000 mowers or two months in between.

So if you can follow my mess.what that means is. Between the model 4 Automatic and model 5 S1 we have only 2 months worth of the PLAIN model 4. Its such a short time frame any thing could have been put on...A: Basic Auto leftover parts or B: A special Badge.
I hope this makes sense.
