In a post below you provided a great deal of information about the 30 Lg.s.F.H. 13 (Sfl.) auf Lorraine-Schlepper assigned to the Afrika Korps in 1942. In it, you noted that seven were lost at sea: a batches of three lost in July, and a batch of four lost in August.
One of my other areas of interest is the attacks by RAF Beauforts on Italian convoys to Afrika. in my research I have acquired Italian documentation for every convoy to/from Italy/Afrika and Italy/Greece. It includes depature dates, attacks and losses, and arrival dates.
You noted three ships having been already loaded with ten of these vehicles in July 1942, specifically Pisani (3), Pilo(4), and Sestriere (3).
The three vehicls lost in July sank with Vettor Pisani. This veteran of the Afrika run was 6,3339 BRT motorship, completed in 1939. Escorted by the torpedo boats Antares and Calliope and the destroyer escort Orsa, she was attacked on 24 July by 9 Beauforts operating out of Malta (combined 39/86/217 Squadrons, RAF), escorted by 5 Beaufighters and hit by one torpedo. Though not sunk, the ship was badly damaged and towed to Argostoli where, the next day, she was bombed & burned out by RAF bombers.
Italian/German cargo ships lost enroute to Afrika in August 1942 were MS Monviso (5,322 BRT, lost 03.08), SS Wachtfels (G, 8,647 BRT, lost 07.08), SS Ogaden (4,533 BRT, lost 12.08), MS Lerici (6,070 BRT, lost 15.08), MS Nino Bixio (7,137 BRT, lost 17.08), MS Rosolino Pilo (8,326 BRT, lost 18.08), MT Pozarica (7,751 BRT, 21.08), SS Dielpi (1,527 BRT, lost 27.08), SS Istria (5,416 BRT, lost 27.08), MS Manfredo Camperio (5,463 BRT, lost 27.08), SS Paolina (G, 5,894 BRT, lost 27.08), ST Sanandrea (5,077 BRT, lost 30.08). If you can identify the ships that loaded the last 10 vehicls, I can supply the details of the loss.
Hope this helps.
