I have a photo of a RCAF Dakota with a tail number of 12857, but am unable to DEFINITIVELY determine its construction number and/or subsequent reg. numbers. The photo was taken at OSH in the Summer of 1985 at Bassler. The Bassler people told me they took possession of some recently demobbed Canadian Dakotas at that point in time, but were unable to tell me its fate. Any help? Thanks.
