I bought tons of these caps from ebay, and so I have about 25 full sets, plus swaps. When I was scanning them in, I went away to get a cup of tea or watch the football, or something, and when I came back, the computer was resetting itself, so I had to scan them all in again! The numbers for these caps are on the front, printed in holographic paint, which makes them very hard to read. However, there are 35 in the whole set, and I think I have put them in the right order.
