Manuel,
Thanks! In the meantime I have found out that the truck is a "OM Tigre".
It's a pity that not much information can be found on these trucks on the internet. I was thinking of a scale 1/24 scalemodel with Abarth's on it. But I have to keep on looking.....(Barnini has a 1/43 scalemodel of the Abarth-OM)
Yes I know Multipla's were used as delivery vans, but Abarth also used other vans for the "servizio corse". You can see on of them on the cover of "Abarth, the man, the machines". Do you know what this van could be?
I have also looked at the picture you discribed on page 196. Probably Fiat
Thanks again, Alex
p.s. Does domeone know if Abarth ever used the Fiat 238 as a "servizio corse"van? I believe "Progetto K" has a 1/43 scale model of it. But was it ever used??
