The Tokyo Plamo kits are to odd scales. The Tsurugi is 1/76, the Betty to 1/226, Invader unknown scale. The rare Odaka Irving is reportedly to 1/71 scale. The Otaki jet fighter kits, new to me, are marked as to 1/144 scale.
Peter also wishes to sell a copy of Japanese Aero Engines by Mike Goodwin and Peter Starkings (MMP Books, 2017) . Condition is very good. A brief review of this book was posted here.
* 'More recent' - a relative term for anyone who remembers buying Frog kits new.
