Stihl 07/07S prototype

[Steffen]

I know a lot of you guys have the Stihl 07 or 07S saw in your collections, and i just want to shere this one with you all... And hopefully learn a bit more about thise great saws.

I got a very interesting saw, its a prototype of the Stihl 07, or a testsaw it might be called.
If its true what the previous owner said to me, this saw was given to a huntersfriend to Nicolaus Stihl for testing before the 07 came on the marked back in 1961. It was given to him because he made a lot of firewood and they needed this saw to be testet.
The previous owner got it from him, so i might be the 3. owner of this saw.

This is my first 07, so might need a bit help from you guys to tell me what is different on this saw than the normal 07.
As i can see, the starter is different and there is no Stihl logos anywere on this saw. The carburatorcover is also different, there is not the normal Stil 07 sign on it. and it seems to be sandcast as it is a bit rough.

And look at that id plate... it comes from a Contra, but there is stampped 1107 and the serial 114069. I have never seen a serial that low before.

I have contactet Stihl about it, and im waiting for them to might confirm this story and maby they know a bit more about the saw.

A little video of it:

The starter is much different than the two 07S saws I previously owned. A very interesting find.

If you strike out on info from the factory, try and get ahold of Wayne Sutton at Stihl Northwest. He has a huge collection of Stihl saws and is an encyclopedia of information.

Its actually Wayne i have contacted, he is on the case ;-)
I was in the US a month ago, and stopped by his museum, its an unbelievable collection he has made!!

He's the rep for my area, he's a first class guy.

Cool saw, even cooler if it is truly a prototype!

Seems to still run nicely.

Im quite shure its a real testsaw, there are so many things on this saw thats not the same as on the production 07. Many of the the parts also seems to be sandcast and sandet down to get a better finnish.
Especially the removeble cover at the back of the saw, this dont have the Stihl and 07 name on it. It also looks to be sandcastet. Also the startercover looks very odd.

Very cool. One of my favorite old saws.

I got a mail today from a collector that also had a testasw...

My teori that mine was green and not had any white one it seems to be right, his is also green!
But his is an even more early testsaw it seems, look at the handle it comes from a Contra.
The rear handle and the rear cover must not had been developed yet, the startercover and upper cover is in one pice like on the 08.
He says this saw dont have any serial, and comes from a farmer that lived near the Stihl factory.

My saw is possible a developed edition of his, but still not 100% as the production 07.

I must say a whole new world of Stihl prototypes is opening up!!

Green color some times were used on Army saws - but in this case I believe more in the prototype/test saw theory. Cool thread!

Im hopeing for some help on a 07S, the piston is broken in one of mine.

So im in need of a new or used piston for the 07/07S.
I know they are not that often for sale, but hopeing someone can help.

Maybe another piston can be used. The 07/07S is 50mm and the wristpin is 14mm

 

[VinceGU05]

maybe can help you.. give me a day or two to have a look in the shed. it will be a used one.

 

[Steffen]

I made a video showing some of the differens i have found between the prototype and the production model.
I hope you can understand my english

I just found an early 07 for the 07 collection. The collection is now complete with the prototype, the 07 and the 07S.
The mission can now begin to list all the changes between the saws...

Here are first step, a lot of pictures of the saws.

First the prototype vs the 07

By the way, the prototype is more heavy. They are both empty of oil and fuel.
Prototype - 9,5 kg
07 - 8,7kg

[Steffen]

And now the 07 vs 07S

Not so much diffrent, but still some small changes here and there

 

[Steffen]

Today i took the 07 prototype out for some testcuts before i will clean the saw up and put it on display in my collection.
It runs quite good

I think Stihl also used a 07/07s powerhead on a brush saw, I had one complete running and gave it to a member here.
But there is another up against a shed next to my cabin, I will take a picture, I can probably have it,, but for what.
It is very heavy duty and you must use a harness its so heavy .
I posted picture here but think they are long gone.

Edit found a pic on AS, not mine and it may be an 08/08s powerhead.
