Thanks for the report.

This appears to be a T3 industrial engine.  The first three digits of the 
case SERIAL # are only sequential, and can be anything that comes up, so the 
111 has no special meaning, but having the rest of the digits might allow it 
to be dated.  Do you recall how many digits came after the 111?  Also 
interesting would be its letter prefix (K or M for the later single carbs.) 
If there was no letter prefix then this engine is a 62-65, on the other hand 
12 V started in 67. This is a single carb version which was one of the 
standard versions, but rarely seen.  I suspect that it might have been much 
more common in the industrial engines.  VW made T3 side draft single carb 
engines 62-73, all were 1500 cc, and I believe they all had single port heads.

I think the industrial engines also often came with a different muffler as 
well as not having heat exchangers.

The horseshoe bracket is probably just a lifting eye.

I've never seen one of these, so I can't be sure what the extra pulley and 
bracket is for.  The AC cars indeed had something like this; in their case 
the pulley was small (about 4" dia if I remember correctly) and located 
completely inside the black steel sheetmetal air duct located just aft of 
the Al fan housing.  AC was only available dealer installed in the US, and 
the dealer had to cut up this shroud to allow the V-belt to exit to the 
right and get to the compressor.  The compressor was mounted to a rather 
crude welded up steel bracket to the right.  This installation pretty much 
mucks up the whole engine. [Is my distain showing through?  I'm trying to be 
kind!]  I know AC was a dealer option in 70, but not in 68; anyone have a 69 
w/AC?

I don't think an industrial engine had to be stationary.  Each of our local 
ice rinks has a Zamboni ice machine that is powered by a VW engine: the old 
one is a beetle engine, and the newer one is a Rabbit engine.  I suspect 
that VW would have considered both of these to be industrial engines that 
were delivered to Zamboni to become part of some other product.  In other 
words, an industrial engine was any engine sold for use other than in a VW car.

This find appears to be interesting, but less and less valuable.  If it 
turns out to be a later version with a dual port case, however, then it 
might be worth picking up for some of the parts.  The single port heads and 
lack of heat exchangers would be its greatest drawbacks.
