RASC Hamilton Centre 1979_06
Scanned by Colin Haig 2006-03-25
Scanned with Nikon Coolscan V ED.
These slides had a date on the slide mount, 1979 06. Not sure when actually taken or when developed. I think what happened was the slides were taken and developed later. The slides are from the construction of the Hamilton Centre Observatory.
Abbreviations: HBF - written on the slides, I think they are the initials of the photographer. HBF is likely H.B. Fox.
