This appears to be the Marsh refractor (largest instrument, or might be McMaster scope, one is a Brashear). Smaller one looks like the Bernier scope made by D.B. Marsh for Captain Bernier's northern expeditions. Not sure what the lower instrument is. The viewing boxes show various magnification of the eclipse in progress. This photo was damaged and someone used white-out to try to fix it.

RASC Hamilton Centre—1932 Eclipse
Scanned by Colin Haig
 
These slides are from the August 31st, 1932 solar eclipse expedition in Acton Vale, Quebec. There was an 8mm film that somebody (no idea who) transferred key frames to 35mm slides. I am not sure when actually that transfer was done or when the slides were developed. I scanned these (2006-02-11 through 2006-04-06) using a NIKON Coolscan V ED at highest resolution.
