What is your question? For those amateurish stampings to be factory, Heinz would have had to gotten really sloshed at die Bierstube at lunchtime.

While the stamping may look amateurish or at least atypical, the engines themselves are rather atypical. I see no particular faults, just that they do not look like a typical production engine. There are not many examples to compare to.

Looks like the genuine article to me. G

While I am not familiar enough with these engines to comment on authenticity, I will say that somewhat sloppy stamping is a hallmark of the factory, at least in the 356 era. In fact, super straight stamps would sometimes raise my suspicions. I suspect most people who do re-stamping would try to be careful and deliberate while the factory line was ripping through it. In addition, a special engine like this was probably not going through the normal process.

the * seem to differ. On the top one it's a thin line, on moito's it seems to be "fatter".

How does this one look? Can anyone guess what engine this is by the number? Of course a 911 engine:

Font looks correct but the engine number seems horizontally compressed. Doesn't mean it's not factory - just not typical. I've seen some variation.

As opposed to the previous pictures, the one above looks like the case was machined and restamped. The others look to have their numbers in a rough finish that doesn't show signs of being machined flat.
