Admiral Graf Spee and an uncertain review-date recollection

Which Royal Review did Admiral Graf Spee attend?

A viewer identifies the 1937 Coronation Review. The initial recollection of 1935 is revised tentatively, rather than settled through a source check during the exchange.

The initial answer tentatively places Admiral Graf Spee at the 1935 review and doubts that she attended the 1939 event. A viewer then identifies the 1937 Coronation Review. That correction is accepted as possible, with an admission that the dates have become confused. The exchange ends with the date still dependent on the viewer's correction and the need to revisit the reference book.
