How about the coloured pencil method?

It's been published by a member of the EM Gauge Society, if I remember correctly, but consists of base coat of mortar colour followed by applying brick tones using water colour pencils.

I've seen a set of replacement (00,EM, S4) frames in etched nickel silver for this kit. I have just emailed the supplier and I'll let you know if they have any stock.

It's a shame that this kit has not been upgraded during the years it has been available. I hope someone does not make a RTR version as I have three to build. All the best with your build.
