Re ; ' My thoughts too Roger. When trying to date the slides, you have to grab every clue that you possibly can. '

Yes indeed, I know that a lot of my Pukekohe photo's were the incorrect meeting - and as I had given all my Pukekohe programme's 1966 - mid late 1970's away and all my Motorman Magazines 1964 - 84 was unable to reconcile pictures with events.
-some were Ok as had written on the back of the prints when the film was processed - somehad dates on the packets too, a few had process dates on the negs and prints - mainly when I borrowed my grandmothers Leica camera and took Colour pics.

Thank Goodness for people like Milan Fistonic on TRS and Facebook pages [ Milan's archives are amazing ] and Graham Woods on a couple of facebook pages too.

TRS is a bit disjointed with all the threads but it is a great collection of information.
Graham seems to have programme's from late 1950's through the 1960's and on - and Motorman Magazine back into the early 1960's
