I was an instructor on the L-180 and drove it for many peaceful, fun-filled years in the Irish army reserve (11th Cav, same unit as Peter O'Kelly - hi, Pete!).
I still have memories of a hairy drive to Dublin after annual training camp with a slipping clutch and fading brakes.
As you probably know, the Madsen guns had also been replaced with Hispano 20mm aircraft cannon as main armament and .30 cal Browing mmgs as coax and hull-mounted secondary armament. The radios were British C12 sets. If you need more technical information, Pete could put you in touch with a former member of the 11th Cav who was very knoledgeable about the cars.
One was given to a Dutch museum while still in serviceable condition - it was driven to the harbour for transport. It's ridiculous that the others were allowed to decay so badly.
In the Royal Army museum here in Brussels some years later, I found a book that contains a photo of one of the Dutch versions of the car, with German army markings, after it had been knocked out by a 37mm Belgian anti-tank gun while in use by the German army during the May 1940 invasion. It's not very distinct, but if you're interested let me know and I'll see if I can either scan it or put you in touch with the association of former members of the Belgian army cyclist unit that produced the book.
