Whilst at a larger, 1/48 scale, on my model of Velox I used self adhesive copper tape for the brass strips holding the cortecine down. This can be got from many hobby stores and I believe is uses in stained glass windows for some reason. If pained with a clear varnish it should also retain is lustre.
It's easy to cut and being self adhesive easy to fix and also very flexible so no chance of differential expansion causing things to pop off.
Hope this may be of interest.
No progress on Velox as now trying to move house!
