Old transfer sheets - Imperial guard.

I checked my old army box and saw my former painting skills ... I was shocked.

I was still young and well, .. no comment.

I wanted to give it a new try, so I managed to find easily good colour schemes for my Valhallan Army, but I would like to keep the old number system.

The new transfer sheets do not have this circle with a number inside.

Does somebody know where to find it? Where to buy it?
