ALEX L.,
From what I do remember, the Lysander Operations were all standard, in terms of Navigation (dead reckoning, visual checking of the "L" on the ground and established signal of the day, etc..). It seems, some Halifaxes and Stirlings that were used on SD Squadrons did have H2S and GEE, some NAV aids for long range trips. If memory does not fail me, there are pictures of (at least) Halifaxes with those gadgets (antenas, etc.).
The PDF file I informed you can be found here:

On page 13 you will find the first accident of Nesbitt-Dufort:
Mission: Operation Beryl II
Forced landing 02.10 due to low fuel and icy plane on returning in poor weather near Coudray farm 2 km S W Saint-Florent-sur-Cher (Cher). Aircraft damaged beyond repair and written off
Pilot: capitaine John Nesbitt-Dufort
There are a lot more on the file....you will surely find it amazing and quite interesting. On the incredible book of SOE in France, by MRD Foot, there are tables of missions and a special chapter dedicated to the Air Operations.
As I told you, I would like to read John Nesbitt-Dufort book, but it is yet on the wish list for Xmas....the book of Hugh Verity is one of the most treasured books I ever read...it is FANTASTIC and I really enjoyed it.
There are several sites about 161 and 138 Squadron and even Tempsford Airfield (with some memorials),etc...
I do not know what you are looking for, but if you need a more precise approach, please do ask here. There are EXPERTS on every field of Aviation History here, from a simple sprog writer-to-be, like me, to Famous writers and persons who read, research and live WW2 History for more than 2 or 3 decades....and we are all linked by this love for the subject, something that is greater than ourselves....(wives do not like this passion, believe me!!! and when we spent too much on books, photographs at Ebay, etc...but "c'est la vie").
All the best and I do hope to have helped...By the way please do let me correct my English writing on the last (previous) posting:
"I am fond of"
"rudder"
Yours,
