CMF escape & evasion packs?

Can anyone tell me about this escape and evasion pack that I have? As you’ll see, it’s labelled “C.M.F. Packs” and contains two silk maps, a miniature compass and cards for translating phrases from English to various languages. I’m guessing the map dates to WWII as one of the maps contains the Nazi German Protectorate of Bohemia and Moravia but, other than that, I know very little about this kit. Is it RAF? What does C.M.F. stand for – Central Mediterranean Force, perhaps?

Here are a few photos:

Thanks for any information you may be able to provide,
