I did a similar thing more than ten years ago. I too had a passion for the Constellation, and did the type rating in Avra Valley, just north west of Tuscon on Vern Raburn's L749A (technically a C121A). After sending a cheque for about USD10,000, they sent a set of manuals and Standard Operating Procedures. I was expected to have them well known by the time I arrived.
Interestingly enough, there was an L1049G parked near YYZ
as a restaurant, so buying a coffee every now and then, I sat in the cockpit studying procedures!

When I arrived, I attended a ground school for three days, then did about 10 hours of flying. The last flight was the "check ride" with an FAA inspector who put the type rating on my US licence. With that in hand, Transport Canada added it to my Canadian ATPL.
Although, everyone acknowledged that it was unlikely I would ever find one of those to fly around. The type rating is still on my licence, as it always will be. In Canada a type rating is permanent, however, to actually legally fly the aircraft a PPC is required to fly it with an air carrier.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!
