Try to find the spot where the photographer was standing.
Taken from somewhere near here . Pontoon bridge is spanning the Royal Canal with the Mullingar to Athlone railway line behind. Newbrook racecourse had its own station which was unique in that it had two platforms which were both on the Down Line. The racecourse closed in 1961 after 109 years.
The floats look like they're made of metal..as if old petrol tanks? The racecourse was used in the making of the 1948 film "Captain Boycott" and can been seen here. It's pretty awful....No! It's much worse than awful..

https://www.flickr.com/photos/91549360@N03 The floats do look like drop-tanks. I wouldn't think they are though - why would there be nine identical drop-tanks in Westmeath, an area not famed for its aero-industry?

I remember the boating lake at Fleetwood, Lancashire had catamarans made of paired drop tanks (at least that's what i think they were) with holes cut into the top and seats inside, back in the early 1960s. I presume they were surplus tanks from the war...
Racing at Newbrook actually ceased in 1967, the final meeting was in July. See the book 'Racing Through The Midlands: Westmeath and Offaly' by Stan McCormack
Mullingar Agricultural Shows were also held here I have a vague memory of been to one mid 60s. IDA developed the site and in 1976/77 GAF an American company set up making vinyl flooring. Then taken over by German company Tarkett Sommer again vinyl flooring who were there till it was closed by them late 1998/99. Factory was demolished in 2000/01 Redeveloped and now Mullingar Business Park. My brother worked at Tarkett factory for a number of years till it was closed. https://www.flickr.com/photos/nlireland
