I've always enjoyed this model. Not to hi-jack your posting, but I wanted to add a few pics of some similar tankers...

In addition to the one you've shown above, Play Art / Model Power also made a version that was a bit bigger. This one marked as Tanker 51and had a few more details like side mirrors, a spare tire under the trailer, and Maltese logo tampoed on the cab doors -



and then Yatming came along and tried their hand at making a similar model (in larger scale), using the same tanker markings but Peterbilt style cab -



and here's a group shot of the three -

Those two other tankers must be really big😬 They look really cool side by side👍😊
