This is in the dreaded grey 25-35 yo area, about which the forum is ambivalent. It looks modern to me. Another truck doing what it was built for: working. This one is a Leyland, but I don't know the model, or where it sat in the product range.

I went back to the original, but it isn't clear there either.
I guess all capitals, so it called be a large H and smaller IPPO. It could be a large B and smaller EAVER. It could be simply Beaver.
Others will know the Leyland style.
