RAF 148 sqdn based Brindis Italy (searching for info on)

[f for freddy]

I am trying to find any info or veterans connected to the 148 sqdn and their base at Brindisi in Italy, where they were flying the Merlin powered Halifax on SOE/partisan missions.
This part of the squadron's career started in Jan 44 in 334 Wing RAF with 624 sqdn (which left in Feb 44 for Algiers I believe)
There also was the Polish flight 1586 with Liberators; I have also read that there was two American Liberator Squadrons that were training in England? Did these arrive in Brindisi, as I know the Americans operate Liberators there and it was its OSS base for Air and Marine operations but I still can't pin down American squadron numbers for between Jan and August 1944?
One of the pictures that I have is of a crashed Lib it shows a Square to the top of the Libs tail plane with a band below it of the same color, also on the fuselage there is a circle of the same color with what looks like an L in it but the main wing cuts the top of the circle of. When I say color I should say same shade as it is a B&W piccie but I believe the intact engine cowl front is color (might be red) the ship is overall silver.
I am presuming the picture is at Brindisi as that is where the crewmember from the 148 sqdn that has prompted my research was based, but it also could have been a diverted Lib from another station.
Any thoughts, leads or ideas would be gratefully received, this is my first steps into major research and would like to do justice for my departed friend who braved many missions (some of the worst to Poland) and lost a lot of good mates in the process
