Always interested in these expert builds, but I do need to restrain myself, as attempting to copy procedures found here, and with the likes of Rob Pulham, or CLAG, have shown up my own inadequacies.😒
Rob, you always seem to work from drawings, which is pretty obviously the way to do it, but where do they come from?
I recently wanted drawings of a BR Britannia, but could only find them suitable for a 5" gauge model and priced at over £100🙄
I know of Isinglass but they are mostly LNER.
