I think you'll find MRP listed at the beginning of the 3rd paragraph of the posted letter. Reloder 22 is an "improved version" of MRP.
MRP is listed in the data of Speer #10, published in 1979, but N205 was discontinued before that printing. That indicates N205 was still available in the non-American market at least 9 years later, when the letter was written.
