I also have some info.
I live in Belgium and recently I got some of those industrial Type4 engines.
They were used in trolley busses in Switzerland, so busses that do not use any fuel, but electricity to drive. They ride around in town and they're always connected to the electricity with two cables on the roof.
The VW Type4 engine was used as a "emergency unit" to produce some electricity, when the electric supply was faulty.
One engine was originally in this bus and has only 35 working hours:
The buses are replaced by new-ones, so the old ones are "recycled". They were used from 1982 until now.
The engine itself has the T127 code, however one has an AP code but is similar to the others.
It's a 1800cc, 50kW, limited to 4000rpm
Here's an identification plate:
They have some double Solex PDSIT 36-40 carburators and electronic ignition. Everything is 12V!
Almost every engine has heater boxes and they are all in great shape! They start very easily and they run like a Swiss clockwork!
I converted one engine with an upright CSP conversion for my 1303S bug and I will soon post a topic about it.
I also took of the heads, to remove the gaskets for a slightly higher compression ratio, and all the pieces inside were like new!
I'm really curious about the driving experience in my bug with this engine...
