This dome stay was marked "1454" by me years ago when I parted out a machine.
It is much stronger and heavier than the Rock-ola Dome Stay # 19021 that is used in models 1448, 1452, 1454, 1455, 1458, 1462 and 1465.
Perhaps there was a change in suppliers, or this is an after market item.

This dome stay is straight but there is rust on the metal finish.

The length of this dome stay is 29.6 inches.
(74.9 cm).
