[1][2] Shinny represented the Munster inter-provincial team at various times, winning two Railway Cup medals on the field of play and a third as a substitute.
Shinny played for Limerick at a time when the team's fortunes were at a low ebb, with Cork dominating the provincial series.
Points from Mick Mackey and Jackie O'Connell and a remarkable four goals from Dave Clohessy secured a 5–2 to 2–6 victory for Limerick.
The win gave Shinny an All-Ireland medal in the golden jubilee year of the Gaelic Athletic Association.
He won his first Railway Cup medal as a non-playing substitute in 1928 as Munster defeated arch rivals Leinster by 2–2 to 1–2.
