A few decades ago – how time flies! – I was at GenCon, and one of the fellows at the Koplow Games booth had his own mini-flea-market. I bought his 'WWII Italian Army' collection, but he told me he did not know the origin of the models. He said they were no longer in production.
I painted the trucks many years ago, but now they've come back to my workbench to be 'upgraded' to my current basing style (1" square wooden bases from LITKO, with FlexSteel on the bottoms for storage in magnet-lined boxes).
I originally thought these were just Opel Blitz trucks being used by the Italians, but I have since identified them as Fiat 626 NLM Medium Trucks.
I'm curious if any of our readers can identify the manufacturer of these models. I would guess that the models are 1:300 scale and probably from the U.K.
