I can't find a service record on Ancestry either, but there is the medal roll which says the following in the column headed "In sequence Units and Corps previously served with by each individual...":
8 R. Ir. Fus. 16576 Pte
7/8 R. Ir. Fus. 16576
1 R. Ir. Fus. 16576
but it doesn't give dates when he transferred from one to another.

The medal index card shows that he received the Victory medal and the British War medal, but doesn't have any further info.
