So, having had the etch in my possession for nearly a year, I though it might be about time I did something with it...
Perhaps showing this might persuade others to order one, as apparently I'm so far the only one who has!
In 7mm anyway...
Here's the components made up...
...and fitted to the wagon body.
The instructions say that fitting of the bar strapping is fiendish, and it's not wrong; I can't imaging what the 4mm version must be like!
