Thanks, yes I like the Javis myself, although perhaps it is a little dark with indoor lighting for a model layout, but that's just a personal preference. I'm going to try two more samples with Woodland Scenics fine and medium buff which is quite bright, but when lightly weathered with sleeper grime may end up looking ok as a compromise. I'm a bit odd because I like scenery and rolling stock to look pleasing to the eye rather than necessarily prototypically accurate.
The brake van came from Irish Freight Models (IFM). Personally I'm extremely happy with it, but I don't want to get my wrist slapped again for praising them too highly despite my personal opinion. They are RTR and not inexpensive, but personally worth it to have three of these iconic brake vans on the layout because all my freight is 2 axel loose coupled stock typical of the 60s era. I like the way he has simulated felt texture on the roof.
Will post more pics of another few ballast samples in a day or two. Need to get my hands on a little PC vacuum cleaner, because a household one is too powerful for recovering surplus static grass (i.e. after glue has set), it can tear it off the base board if you get too close even 24hrs after PVA has set.
