Those wagons have always been a favourite of mine. I've been contemplating starting on a rake for a while now, using the usual donors. But then I keep telling myself, maybe a certain manufacture will eventually release an oil - molasses wagon.
It's ignorance, Dave. Hoarders, generally collect pizza boxes, newspapers, empty milk cartons, etc. Not €500 models. Or maybe that's just me stereotyping.
I've bought a few of the Hornby double packs recently, and agree, they are very good models. As you've said, the print is definitely up there with C-Rail, and containers themselves, have some really nice detail.
