Thanks David. Actually it was pretty therapeutic making a batch, by the last one I had an idea what I ought to be doing! And of course, a batch of wagons makes it more worthwhile getting the paints out. There are another three vans in my box unstarted, but I'm determined to work through a swathe of unfinished projects first. As well as the banana decals, I acquired GUV, Palbrick and Grampus, so a fair few items should be moving to stock boxes in the near future.
As you say, some trader labels would be a good idea; I didn't check the CCT list, but I'm sure he'd be willing to give it consideration especially if they're available in larger scales. He seems to have a massive range, some items being very esoteric.
One thing I did learn, the CCT decals don't take kindly to enamel thinners. I learnt the hard way, it probably mentions it in the instructions!
