DECALS FOR A SWISS 109E HELP NEEDED

Hi All

I`m building a 1:48 109E in Swiss markings and I need Help.

No not from a mental viewpoint. The kit is built and painted, the dio base done and I`ve hit a brick wall. The a/craft has “J-311” in white on each side in letters that scale out at around 6mm high.

Can anyone help on a source for these, a friend suggested rub down like Letraset which is fine as I can fix this to clear sheet and apply like normal.

All info gratefully received

This aircraft was built by Randy Lutz in the May 2006 edition of Model Aircraft Monthly. He used AeroMaster sheet 48-034 which has decals for J-371. This was too gaudy for his liking so he used two sheets to get the ‘11’.
