Many thanks Paul, it worked perfectly. Red, black, yellow and white wax available from the supplier who has a website

where you can order without bidding on eBay. One more tip (after a bit of practice!) - I used an old credit card to scrape down the excess wax and this gives a smooth finish flush with the brass without scratching. The solvents in Brasso appear to dissolve the wax too, so if you want a nice polish, do this first, fill with wax, scrape down and then remove any final wax traces with a spot of white spirit or meths on a rag. Now to do a couple more plates! They look exactly right.

Kind regards and thanks again!
