Mitchell and Ness made these a couple years ago not sure it they still do, not exactly what you are looking for but cool. You might be better off getting a really thick shawl collar cardigan and make it yourself with felt. That is what the sweater type you are looking for is called: shawl collar cardigan. Would be easy to find especially if you are looking for navy or grey or black. You could get the letters or logo print it out and cut the felt to work. Might be cool and look old and imperfect which Im sure the original old ones were as well.
