Had the Germans wanted the Mailie they would've gotten it, infact they almost certainly already knew most of the things worth knowing about it, the Abwehr being all over the Italian armed forces. However the Germans had no use for it in late 43, and so a procurement of one wasn't even considered.
The chief Abwehr operative in the Italian Admiralty was the KM naval Attache. I think his name was Raus, from memory.
I am not going to assert that the abwehr didn't know about Chariots, but neither is ther any evidence that I know of to say that they did know of it. If you have evidence to the contrary, I would like to see it.
In fact the circumstantial evidence very strongly suggests otherwise. The reports that I have seen (but I cannot now find) suggest that the OKM was very surprised by the equipment, and the success of Chariot attacks in November. Moreover, what is not so well known is that the 10 MAS had been operating for some months out of a disused merchant hulk, anchored across the bay to Gibraltar, in the Spanish port of Algerciras. The British had been unable to locate the source of these attacks. This small group of saboteurs managed to sink over 100000 tons of ships in Gibraltar, and were never caught. The british did eventually get a good clue as to what was happening, but this was never the result of covert intelligence. Now, if the germans had known about this they would have talked about it, and if they had talked about it the british would have found out about it, because the german security services were basically a swiss cheese with holes all over it, when it came to the SOE. There has seldom been a more compromised security organization as the abwehr. Moreover there is also the weakness of Enigma, which throughout 1941, the Allies were reading
The Italians had a weak security service as well, but it did not suffer from enigma style breaches like the germans, because they didn't use it (until 1942), and their own security services were actually superior to the Abwehr 9there wwere other security organizations, namely the B-Dienst service, the SD and Gehlens team attached directly to OKW. But none of these services had operatives working in Italy in 1941.

But again, had the Germans wanted it they would've gotten it, either the easy or the hard way. I'm sure the KM could persuade the Italian Navy to hand over a few examples of the Mailie in exchange for some KM hardware. If not the Abwehr could simply steal all the plans.
The german intelligence services were not on a par with its armed forces. The abwehr was basically the laughing stock of Europe, because all the intelligence agencies knew that they could sell any story to the organizations and it would accept it, hook, line and sinker. The german intelligence system suffered from being over rigid, and too centralized in terms of its control. This prevented many of its spy networks from employing the sort of quick thinking tactics that were needed in order to work successfully as a spy. Moreover, the over rigid approach taken by the abwehr meant that their operatives were generally very easily identified and compromised. In England for example, there was not one German spy that had not either been captured or compromised from early 1941 on .
Whilst I cant prove which spy service (Italian or German) had the upper hand, my suspicions are that it was the Italian. The italain spy service was nothing like the Italian military, it was actually quite efficient. For example, the Italians predicted, with a great deal of accuracy, the Torch and Sicilian landings, whereas the Germans were basically floundering.
Certainly, if the germans did know about the Italian chariots, they did not act on it, until after the November attacks. After that, they, in common with nearly everybody else, wanted to get their hands on the technology. AFAIK, they never did, and the proff of this is in the rather p[oor efforts they made in the form of the Neger and the Marder minisubs, which were based on the same general idea.
Lastly, the 10MAS outfit was the crème de la crème of the Italian military, It was a thoroughly professional outfit, full the equal to anything in any other army, and not an easy organization to penetrate when it came to its most jealously guarded secrets.
An overt "raid" would have had disastrous impacts on Italo-German relations. Are you suggesting that you would jeapodize the whole southern front, for the sake of delivering 4 Chariot attacks against the Americans. This really is getting a bit silly.
Now moving onwards, how would you guys equip the 25 man teams set off on US, Canadian Alaskan soil ?
Err equipping 25 man teams from U-Boats. Considering that each type IX is able to carry no more than fourteen men , exactly how many teams are we talking about. Given that you will want to so lavishly equip these teams, I estimate that you will need at least 4 boats per team. I don't know how many type IXs there were at this time, but it wasn't many. Each boat was basically sinking about 100000 tons of shipping per patrol, so, if youo are pulling these boats out of the subs available for tonnage warfare, as you must, in order to train the crews, and modify the boats for the operation, then you have foregone the loss of about 800000 tons of British shipping per team, and for what??????/
