Three more TT slides to identify, please? ..rider? .. location? .. marque?  all are dated June of 1970.
TIA!

First shot is a 250 TD2 Yamaha, last shot is a 250 Greeves Silverstone, not sure on middle shot.

1 & 3 look like they may have been taken just before Ginger Hall.  2 is from Creg Ny Baa and is a 125.  Looks like an expansion chamber coming out from the fairing, so a 2 stroke - maybe a BSA Bantam.  No idea on any of the riders though.  Needs someone with a programme!  They helmet design on 1 looks a bit like Gyula Marsovsky but I would have thought he'd have a higher start number.

Great info thanks so much. back in the '80's I had a chance to pick up a running but slightly tatty Greeves Silverstone for 600 quid and passed it up, to my everlasting regret.
I will post another Quarterbridge slide with mystery rider and bike in a separate post... regards

Pic 3 may be P E Platt (Peter was it?) who is the only rider I can see featured in the results of the 1970 250 TT who was riding a Greeves.

Pic 2 looks like a 2 stroke single.  There were 4 Maicos in the results - we already know this isn't Borje Jansson and it certainly isn't Tommy Robb.  The other two riders on that brand were Harold Cosgrove and C Ward, so maybe one of them?

Pic 1 - Not a clue!  It isn't Marsovsky as he wasn't in the race.

All the pictures are sorted out! They are from 1970.

Number 98 is Peter Aitken (maybe from South Africa) on a 250 Yamaha.
Number 53 is Don Ryder on a 125 Bultaco.
Number 70 is Peter Platt on a Greeves 250.

All according to the official program and result lists from 1970.

Silja....you're very good!

Don Ryder, who incidentally is the owner of Darley Moor, was for many years the A.C.U Chairman.
Nice bloke.

Thanks so much for your kind assistance in sorting these! regards, steve
