As of January 13th here is the latest 'quiz' ... as can be seen more sidecars, looking to identify, thanks again.
   
1. Slide dated  'JUN 70' by manufacturer:



2.  Slide dated  'JUN 70' by manufacturer:



3.  Undated slide and may not be I.O.M. (below)




4. Only identifying mark "Post TT 1975"  and no date on slide (below):

I'd say Picture 4 is Dick Greasley at Mallory Park.Not sure of the passenger.Possibly Cliff Holland.

I thought picture 1 looked like Trevor Ireson judging by the helmet colour and design.Had a look at some old photos on line and found one from 1969.Same bike as in your picture.According to the TT database,in 1970,he's on a 500 Triumph and passengered by D.H.J.Lockett .Not sure where it's taken,Creg ny Baa perhaps?

I'd say it was taken between the Bungalow and Hailwoods.

That might be a good call on Trevor Ireson Eric. I think the shot is taken coming out of the Bungalow, just after the bridge.

Yes,I think you're right.
Saw the right hander in the top of the pic and thought it was the Creg when you could watch from the inside of the course.

Found the programme on line.Dick Greasley and Cliff Holland on the Chell Yamaha.Post TT meeting ,Mallory Park 1975

Don't know who it is but I think pic number 3 is coming out of Townley's at Darley Moor

Picture 2-Found a couple of pics of this outfit at the 1970 TT.The captions say it is Ron Smith and Jack Forrest on a Triumph.However on the TT database the passenger is given as Ian Forrest.Jack Forrest is down as riding a BSA passengered by W.A. Forrest.Both outfits appear to have finished in the 750 race,although Jack Forrest was a DNF in the 500.So not 100% sure who was the passenger for Ron Smith(can't see the wood for the trees with all these Forrests about)

Pic 3 now has a firm ID. Over on Steve's Place Dick Tapken identified himself along with passenger Kenny Durham. The outfit is a Windle Imp.

Curious as to where Pic 3 was taken, I'm going to take a guess at Darley Moor, but it is just a guess.
