Good spot on the 150M with the pre-select flaps - I thought all the Ms had them. definitely the 40° flap was more 'fun' than 30°...
Leave the manual question with me - I may be able to get hold of them tomorrow. I 'lent' various manuals to my local friendly aircraft paintshop (Mick Allen & Son) years ago and I think they still have them. I've got to go to the airfield tomorrow so I'll see what's there with them and if the info is there, I can scan it for you.
From what I recall, the IPC for the FRA was a supplement to the F(A)150 manual.
