Hello
This is the badge worn by members of 2 GHQ Liaison Regiment CM. The unit was formed in Italy on 29 January 1945 and disbanded in September of that year. The unit also known as 'Phantom' did not wear the normal badge worn in the NWEurope. It is extremely rare and probably priceless. On my website you will find my drawing of the badge.
I am researching and writing a history of the unit and have published some material about the unit. I would very much like to discover more about your father and his service with the unit. One of the former members of the unit is publishing his autobiography in the New Year. I have published a history of the unit based on records.
With best wishes
