We, at Asian Air Arms Special Interest Group (SIG) of the International Plastic Modellers' Society, have just released a series of post-1945 decals covering all air arms in Asia. They are generic (roundels and fin flashes only) and are printed in four sizes so they can fit most models and scales.
They've been made at low cost by the SIG, intended to help members and other modellers build models from almost any Asian air arm. They're printed on either White or Clear decal paper (you trim them) and until November 11th will be sold for just £4.50 per A4 (11 3/4" x 8 3/4") decal sheet. After then they'll be £5.00 per sheet plus postage of course.
