I've done a crude version (I haven't got photoshop at the moment). It's very low res so short on pixel detail. But better than not having a pic, right

This version probably isn't great for printing, Rootschat restricts the size, including the version of the one you posted. But fine for online?
Someone who knows vehicles might be able to date it.
If you want a printable version of this, message me your email and I can send a 4x3 inch print at 300ppi (which would print at 5x3.5ins at 240ppi).
