Ferret on Parliament Hill during the October Crisis - pic ID

[David Cussins]

After looking at the photo a good bit...i see two points that tell me this is not 589.....first in the photo the ferret has the british tower style side lights....second the socket for the m. g. Mount is an original unmodified mount....i have photos of my 589 as it came out of canada and she had u.s. m series side lights and the m.g.socket was a modified mount from her service in cyprus....these things tell me the photo is not 589........539 maybe???
