6th Airborne Div Signals - Op Varsity help.

I've been researching 2329496 Cpl Colin Roy Lewis and have gone as far as I can. I have his Army Service Record which confirms service in the Ardennes and on Op Varsity.

Paradata also has an entry for him: "Colin Roy Lewis enlisted as a boy soldier in the Royal Signals in July 1939. He volunteer for airborne forces early in 1944 and qualified as a military parachutist on course 112 which ran at RAF Ringway from 17 April to 7 May 1944.

Colin Lewis served in Europe and Palestine with 6th Airborne Divisional Signals before transferring to the War Office Signal Regiment, where he was promoted to Sergeant".

I managed to get a copy of his medal index card (before it was removed), it doesn't really add any more to the story.

Basically, I'm trying to find out if Colin jumped on Op Varsity or was glidered in.

As we know, chalk lists are very hard to come by but, if anyone could shed any further light on Colin's Varsity service, it would be most appreciated.

MTIA.
