Default Which O.S. engine is this???

I bought this engine NOOB (New Out of Box) from a fellow about a year ago, but cannot locate the paperwork. I think it was an "F" or "SF", but cannot remember.

It needs a muffler. I have e-m'ed Tower and Macs but have yet to hear anything.

If someone could help me identify it, life would be much easier.

It is here: http://home.internetcds.com/~barbados/os61%20copy.jpg

It is apx. 33.85mm center-to-center for the muffler mounting holes.

The exhaust opening in the engine is apx. 21.45mm long and 8.8mm high.

The only other marking on the engine is the number " 6707" on the back housing, OS MAX on the left and "61" on the muffler side. It appears to be a ringed engine.

Any help would be greatly appreciated.
