Is anyone able to assist with the following please?

We have a signed print purchased several years ago of "three" Spitfires.

The only information available:

S/L ( Squadron Leader ? ) H. H. Booth

The caption reads...." Swing low sweet chariot "....spitfires of the RCAF on a low sweep.

The print is dated 1943.

Unfortunately there is no mention of squadron number or anything further.

It would be much appreciated if anyone could provide any details on S/L H.H. Booth.
