According to Guy Fay's data book, and to the parts cd, Super M was available as a dual fuel, so it could have had the dual tanks. Check the serial tag on the left side of bell housing. If a super M it will say SM

Grampa's SM had the two tanks.

I would think that a dual fuel Super M would not be a common tractor.

Chances are it is a regular M that someone or a dealer repainted many years ago and all they had on hand were super decals. Or perhaps the farmer/dealer wanted to have a "newer" tractor. My grandfather's super A had been repainted and regular A decals applied. Originality wasn't thought of much back then.

What John said, pins usually don't drill out easily.

If you have not tried it yet , If it is off the tractor or where there is no fear of fire, soak it good with wd 40 or kroil heat up let set for a short while and hit it again with wd or kroil it will suck the oil right in the warm up again and punch it out. it will come loose , just paitence, drilling a roll pin can be tricky it will grab often. and you May damage the hole greatly.
Have removed numerous tough rusted items with this method.

That statement is worth repeating. Roll pins are made of really tough material. Your drill bit will drift into the softer surrounding material. I have never found one stuck that badly. If the surrounding part is well backed up, they knock out with a proper sized punch. Getting the right sized punch makes a big difference. Since they are hollow and springy, rust doesn't bind them in place the way it does other fasteners.
